I was able to solve my problem with slow speeds. I don't know what causes it, but I have read in a few places that it seems to happen with Routerboards and Arris cable modems. I solved my problem by replacing the Routerboard 750GL with a new router from Ubiquity (an Edgerouter X). The specs are simi...

Bill

I am having the same problem with Cox Cable. I have a SB6182 modem connected to a RB750GL. The circuit is provisioned for 25mb down and 5mb up, which I get connected directly to the modem. I have a /28 block and the RB750 is connected between the modem and the primary router strictly for routing of ...

I emailed a support output file. My 6 built-in Intel 10/100 ethernet ports all stopped working after upgrading from 6.22 to 6.23.

Bill

I have 2.8.26 running on a PIII/512mb with an APC UPS1500 attached to the serial port. I'm looking for a script that will email me the UPS temperature on a regular basis. A script that will monitor the temperature and send an email when it rises above 35 degrees would be great, but I'll take whateve...

Bill

I updated my router to 2.8.26 and it didn't solve the problem. So, I restored the last backup file (from Feb 27), and rebooted the router. It has fixed the problem. I'm not sure what the config differences were. I'll have to go through it and try to spot any changes. This configuration is talking to...

Bill

I ran into the same problem a couple nights ago. The web-proxy has lost the ability to talk to the DNS resolver, and times out on every site. No new sites are being stored in the DNS cache. I'm running it as a regular proxy, and had to go change the web browsers on a bunch of systems to get them sur...

Bill

You need to add a serial card that uses one of the standard serial port addresses (3F8, 2F8, 3E8, 2E8) for it to work. Most of the PCI serial cards use a non-standard address and have to have a driver loaded for them to be recognized.

Bill

It got up to 6GB with no problems. I cleared the cache and started over when I upgraded to 2.8.24 about 3 weeks ago. It's back up to 3GB now. So far, there are only 7 PC's using the proxy, so it doesn't accumulate very fast. I put a 40GB drive in because the was the smallest I could buy. The 29GB si...

Bill

I received a similar error when setting up my web-proxy. Just enable it and it should work. It will take it a little time to setup the file system on the drive. How much of the drive you can use will depend on how much RAM you have installed. I have a 40GB ultra DMA drive with 512MB RAM on a 1Ghz P3...

Bill

As I understand it, and in my experience, the traffic flow has to stop completely. I believe a 1 second stop is enough to reset the timer. Most of the internet traffic is in short bursts. If you give them a 60-75 second burst time, web-surfing and email will be very fast. They can also download smal...

Bill

The newer versions of the Acrobat reader will now let you select and copy text from PDF files. It will still require some work, but this should make what you're trying to do much easier.

Bill

Bill

You have the right idea. I think the best thing is to setup a queue for each user. For the users that have a speed cap, set their Max Limit to their speed limit and set the Limit At to something small like 5k. For the users that don't have a speed cap, set their Max Limit to whatever your maximum sp...

Bill

If you don't put anyone in a queue, then bandwidth is given out on a first-come,first-served basis. To give someone guaranteed bandwidth, they need to be in a queue. To give unguaranteed bandwidth, leave them out of the queues. Using the queues lets you provide some QOS and enfore speed caps. If the...

Bill

Look at this thread. If you set the Limit At to 0 and Max Limit to 64k, it should do what you need.

http://www.mikrotik.com/forum/viewtopic.php?t=2138

Bill

Is there a way to give unguaranteed bandwidth to users... for example to give to one user (ip) a unguaranteed bandwidth of 64kbps ??? if traffic is high then his speed would fall under 64kbps, but if traffic is low his speed would be maximum 64kbps... Just use the example given above and set the Li...

Bill

I believe you need to upgrade to 2.8 to do this. I don't think Simple Queues were in 2.7. Here is one of my queues with burst, setup using Winbox. All settings are on the General Tab. Settings are given as tx/rx (upload/download). Name - 2.201/32 Target Address - 192.168.2.201/32 Limit At - 65536/13...

Bill

Use the burst feature in the simple queue. Set a burst time of about 75 seconds. This will allow browsing, speed tests, email retrieval, and small file downloads to run at the maximum burst rate. If they download a large file, it will throttle them back to the maximum speed after 75 seconds and keep...

Bill

Look at DansGuardian and see if it will do what you need.

Are there any IP addresses (public or private) assigned to, or handed out by, MT-A that are the same as any IP addresses assigned to, or handed out by, MT-B?? Do you get the duplicate IP error just connecting the boxes together, or does it only show up when RIP is enabled?? If each MT box has it's o...

Bill

You don't need RIP to just connect two MT boxes together. What kind of traffic are you wanting to pass between the two MT boxes? Just connect the boxes and assign different IP's in the same subnet. You may need to setup an EIOP tunnel over the connection, and possibly put some static entries in the ...

Bill

What interfaces are you enabling RIP on (public, private)?

How are the MT boxes connected to each other (or are they)?

Are any of the clients using routers with RIP enabled?

What are the IP addresses of the clients that get the 'duplicated IP' error?

What is the reason for enabling RIP?

Bill

My DNS cache size is limited to 2mb, but rarely goes over 250k. The entries are deleted after their expire time is reached, the longest is usually 72 hours. I would imagine if the cache fills up, the oldest entries are dropped to make way for the new ones.

Bill

I would suggest you try using the MT box as your DNS server. Under IP-DNS, enter the addresses of the two DNS boxes to use. Enable the option to allow remote requests. This way your clients only need one DNS address. They query the MT box and it querys the DNS servers. It returns the data and stores...

Bill

Loading SP2 automatically enables the Windows firewall. This is probably blocking your PPPOE connection attempts. Have them go to the Security Center and disable the firewall and see if that solves the problem.

Bill

When you enable RIP. the routers talk to each other and share routing tables. If you are using the same Private IP ranges on each MT, then this will happen. If the clients have routers with RIP enabled and their private IP ranges match one of your MT boxes then this will also happen.

Bill

It is usually better to run your own DNS servers. The purpose of DNS is to convert url names to ip addresses. The faster this is done, the faster the link to the address is made and the web page loads. If the DNS servers are on your network, this happens much faster. If one of the upstream servers g...

Bill

It could be that the problem is from the other side. Maybe the servers they are trying to log into are being rate-limited. Remember that the upload for most connections is usually much lower than the download. Many service providers are using the P2P control features of MT to keep this type of traff...

Bill

How are you trying to get the time signal from the GPS unit into the MT box? Does MT actually support what you are trying to do? If you are able to get the time from the GPS receiver using the Motorola software, then I would say it is a communication problem between the units and not an issue of how...

Bill

Thanks. My situation's a little different, so I'm not sure if that will work. I guess I'll have to think a little more, or wait for 2.9 to be released.

Bill

Change 'Require Encryption' to No. Don't mess with Advanced settings in XP client until you get it working. You need to get a good starting point, and then you can tweak until it breaks.

Bill

FOUND IT!!!! I found a new way to bond the ADSL! Well not that new but I can do it now. The first test we did with two ADSL lines bonded the uploads and downloads. So it looks like I have a winner! In the morn I'm going to test it at a location that the ML-IP product did not work at and if it works...

Check the RouterOS Community Support Archives, about 1/3 of the way down on page 3. The archive links are towards the bottom of the main page (Forum Index).

Bill

I was seeking a way to not make this a seperate network segment by adding a router or changing the MT to route. Actually, it is better to have the customers location as a separate network segment. Using an inexpensive router at their location accomplishes this. You really don't want all their netbi...

Bill

Usually, for a CPE unit, the limitation on the number of MAC addresses is on the ethernet port. This lets you use just a switch or hub to attach multiple PC's to the CPE. Some manufacturers use this for feature distinction between the consumer and business models of the CPE. Some CPE units only allo...

Bill

It may get overwritten by newer information, but the cache data on the hard drive doesn't seem to get erased. The counter restarts every time a page is accessed. If the html page header doesn't provide an expire time, the default of 72 hours is used. This can't be changed, and you don't really want ...

Bill

You can use Winbox to setup and monitor the cache. You do not need to format the drive before installing, but you can to verify that it is functioning properly. After you install the drive, you tell MT which drive to use for web-cache and have it format the drive. MT has a stats page that shows how ...

The 3com POE injector is an 802.3af compliant unit. It provides 400ma @ 48vdc. If my math is correct, that should be 19.2 watts.

When I brought my new router on-line, I had trouble getting it to recognize the UPS that was connectged to the old router.

Using Winbox, it shows up under IP-Web Proxy-Settings-General. Second to last item is Cache Drive setting. My choices are System and Secondary-Master.

So does RouterOS support a CF card with OS on it and a seperate SATA drive for the cache all in the same box? It supports a CF card to boot from and a separate IDE drive for the cache. My proxy drive is a 40gb 7200rpm WD with 8mb on-board cache on a Ultra100 IDE interface. Someone else will have to...

Since 2.8.12 is available, they are no longer available on the MT site. I've got it here somewhere, if you would like me to email it to you. There is also at least one individual here that archives all the versions. I read the post, but can't remember who.

Bill

Use the latest version. 2.8.12 was released on July 16th. If it does not work, create a SUPPOUT file and send it to support at Mikrotik.

Bill

There are several ways. If you have enough IP addresses, you can plug the server and MT box into a switch that connects to the feed from the upstream provider. You can also setup 1:1 NAT so that all traffic headed to one of the Public IP's on the MT box is routed to the server. You could also put in...

Bill

The Limit-At speed is the guaranteed minimum speed the customer should get. If the router is heavily loaded and can't provide the 256/512, it will try to give the customer at least 64/128k. If you leave Limit-At blank, then it is a best-effort service and the customer gets whatever is available.

Bill

Thanks. I'm going to try the VRRP soon. I'll post if I run into trouble. I'm not sure on the DHCP. I assign everything static and only have a DHCP pool of 8 addresses for temporary connections. The only potential problem I can see is if the Master and Backup router both try to give someone the same ...

Bill

The Target Address is the IP you are controlling the speed for. The bandwidth limits are in the format upload/download. Leave Destination address at 0.0.0.0/0, queue type as default. The Limit-At setting is the minimum allocated speed for the queue. The Max-Limit setting is the maximum allocated spe...

Bill

You can use simple queues to control by individual IP's, or by groups of IP's. If you put in 192.168.2.176/32, it assigns a bandwidth queue for that IP address. If you put in 192.168.2.176/28, it assigns a bandwidth queue that is shared by that group of IP's (176 to 191). Queues are processed like f...

Bill

You avoid the problem by assigning everyone static IP's. You use a simple queue to control bandwidth by IP, or group of IP's, and put the unassigned IP's in a queue with a very low speed setting. The advantage here is you always know who has which IP address, and you know who to turn off when they p...

Bill

I'm actually more interested in your VRRP setup and all the steps needed to make it work. I've been planning to set this up on my network. I think if you set the DHCP server on the backup router to hand out the same block of IP addresses, you should be okay. The renewal process should be automatic a...

Bill

Trying to mark traffic based on a MAC address seems like a difficult way to limit bandwidth. Just use a Simple Queue and limit it by IP address. You can limit by individual IP's, or by groups of IP's. I would just put an inexpensive router on the other side of the bridge and use a simple queue to li...

Bill

Are they using Internet Explorer? Under the Advanced Tab for Internet Options is a check box to use HTTP 1.1 with web proxies. It is about half way down the list. Check that and see if it helps any.

Bill

Many people use DSL. There are various types of connections. You need to verify with the Provider that your intended use does not violate their TOS. You need to make sure they offer some type of SLA or uptime guarantee. You also need to findout if the bandwidth is guaranteed in any way, or if it is ...

Bill

The link Normis provided shows the reference in the manual to the 'cache-drive' option that lets you select which drive the web-proxy cache is placed on. Having the option to choose a drive shows that MT supports use of more than just the system drive. Since being able to use a second drive is depen...

Bill

Check to make sure the User executing the script has sufficient rights to do so. It may be created by Admin, but someone else may be set to run it in those problem locations.

Bill

Yes, this can be done, and is very easy to do. Just install the drive and boot up the router. Under the IP-Web Proxy-General settings you can select which drive to put the cache on. There are also options to Check and Format the drive. It takes about 15mb of memory for every 1gb of cache, so size ac...

Thanks, much. I really appreciate it. I'll have to print this out and look it over. I've been using a P166 with 48mb RAM and a 2port Intel card. It worked quite well. It's now the backup router. I found a 1ghz PIII with 512mb RAM and added a Routerboard44. I plan to add a 40gb hard drive and enable ...

WJW,

For some reason it didn't show up. Could you send again when you get a chance?

My clients are all NAT'ed. I throttle each one by IP address with a Simple Queue that controls both upload and download. The only Mangle rules I have are to add Normal and P2P flowmarks to the traffic. Do you have your Mangle rules set to Passthrough or Accept? I have read this can affect queue proc...

Bill

The queues were change in 2.8. It is no longer necessary to mangle the traffic and use trees to control clients. The only mangle rules I have are passthrough flowmarks for normal and p2p traffic so that I can use a queue tree to control p2p speed. All the queues to control client speed are simple qu...

Bill

Glad to help. It took me some time to figure it out and get it working. The manual is good, but not always as clear as it could be. :)

Bill

You just enter the limits with a slash. For a 256 upload and 512 download I use 262144/524288.

Thanks for the response. That looks real close to what I am after. I would like to look at the full config, if you don't mind sending it.

I have a MT Router (2.8.11) with a 4-port Ethernet card. I'm using 2 ports, one (Public) connected to the T1 router, one (Private) connected to all the servers and radios. The 2.4ghz network is routed (Proxim MP.11) and the 900mhz network is bridged (Alvarion). All the clients have private IP's and ...

Bill

The simple queues now allow you to control upload and download speed with one entry. The client IP you are controlling goes in the Target Address box. Set the interface to All. It should work without setting any of the Advanced queue settings.

Bill

John, Is 2.9 far enough along that you can tell us what changes to expect? Like what new features it will include? You give little answers here and there, but nothing clear and definite. I believe they are asking if you will Post a Beta Topic with this information. We are also curious when public be...

Bill

The problem is that the information used by the OS when the hard drive was setup is not the same information being reported by the BIOS at boot time. This gives you an error and a system that won't boot. Go into the system bios and look at the hard drive settings for the CF module. You will probably...

Bill

I use the burst on my customer queues so web browsing and email seem very fast. This traffic is usually light and in short bursts. As soon as they start moving large amounts of data, like downloading files, it throttles them back to the speed they pay for. I give them 150% for 90 seconds. I set this...

What version are you using now, what version did you start with, and how long has the disc module been in use? Sector writes can not be totally avoided, but the number is way down in the 2.8.11 I am using now comparted to the 2.7 series I started with. The recommendation I received was to replace th...

Bill

Try Manual config for the disc CHS, instead of Auto setting. You may also need to turn off LBA. Even though you can see and format the drive, you can't always boot from it if the bios and OS don't see the same parameters for the drive.
