hi every one when you setup any hotspot server you will find the filter rules shown in the image down ..these rules add themself forcely and autmaticaly even if you reboot the router board ....why ? , how can i remov them terminally ? thank you very much http://i.imgur.com/S3un8Jl.png You can´t.

Hi,

You´re most probably using the wrong classifier (src/dst swapped) for your queue.
Try to swap the classifiers, or post you config.

It looks like wireless "tx-power-mode=card-rates" is not supported anymore... however, the command still exists. Does anyone know why? P.S. Not sure if it's from v6.12 or before, since I upgraded from v6.0... Same here.. isn't Card Rates better than All rates Fixed mode? i don't think it ...

Hello, Wine lacks permissions to bind ports <1000 for security reasons; at least in my case on OpenSuse. I got the same error till i ran "setcap cap_net_bind_service+eip /usr/bin/wine-preloader"; Maybe, do the same for "/usr/bin/wineserver". You must have "libcap-progs"...

As far as i remember there was a hardware bug on the early RB800s, which led to incorrect temperature readings. We currently still have 2 of them running, without any problems so far but with ridiculous temperature readings. Soon after the issue was fixed; Still have one RB-800 here with a temporary...

We had a Cisco 3825 before, with 2 additional ethernet cards (ridiculous expensive) and memory extension for full-bgp;
But this one was not able to handle more than 400Mbits/s.

poli5681

I got an offer a while ago to replace our core router (because of higher bandwidth demand) with Cisco ASR 1002 and ASR-ESP (5Gbit/s); The specs are not really near the CCR, but it´s price is more than 20 times higher. Just a sidenote: We had to replace the router ealier than expected and did it with...

poli5681

You could do this with NAT of course, but i wouldn´t recommend doing so. I´d let the router do the job by simply adding an IP to both interfaces (like you already did). Then add a static route to 10.202.100.0 for your clients somewhere (at the clients or at your default gw) and do the same for the p...

poli5681

Yes it does; But the biggest issue (at least in our case) was the hash-algorithm.
We got 3 times the throughput by switching from sha1 to md5.
Maybe this will help in your case too.

Hi asterisco, We´re pushing ~400Mbit/s BGP through a RB1100AH with 50% max load; But without conntrack and therefore without firewalling - generally this costs a lot of resources... I´m guessing it should work flawlessly with RB1100AH X2; To be 100% safe you could go for a AS1000 Series (sorry Mikro...

If you bridge the interfaces, there won´t be any routing in place; Why do you need the RB450 then? You could simply use the Cisco Switch alone. If you want the RB450 as a transparent packet filter, just remove both IPs on the Interfaces and assign an address on the bridge interface. Additionally you...

poli5681

1. Yep
2. We´re using them as transparent QOS-System; Therefore we´re able to bypass the box in case something goes wrong...
3. No
4. Yep
5. I could; But simply said our 1100s is tranparent between our Network and the Customer Net. So switching to bypass simply disables QOS

Hope that helps.

Have a look into PCQ; This should meet your requirements:

http://wiki.mikrotik.com/wiki/Manual:Queues_-_PCQ

poli5681

Yes, i´d recommend setting the interface instead of the local IP in rule 10.

Anyway i just noticed, that your rule should work (according to the packet flow diagram in the wiki).
I just tried on my own and it works.

Does it work, if you remove your final drop rule (Nr. 11)?

poli5681

Filtering is done before NAT; Meaning you have to use a filter-rule like this: 10 ;;; allow public services chain=forward action=accept protocol=tcp in-interface=ether1 dst-port=80,443 or 10 ;;; allow public services chain=forward action=accept protocol=tcp dst-address=YOUR-WAN-IP dst-port=80,443

poli5681

Do you see any errors or drops at the interface statistics?

poli5681

You dont´t need Level 4 for PTP Setup. Just set Mode "Bridge" on the first and Mode "station-bridge" on the other - no need for WDS. http://wiki.mikrotik.com/wiki/Manual:Wireless_Station_Modes#Mode_station-bridge Additionally you have to add a bridge and bind both wlan and ether ...

Hi saintofinternet, Usually there´s no need for VPLS on PTP Links anymore; RouterOS V5 has a native Bridge Mode without the speed tradeoff using WDS; Said that, you won´t get good results at you test setup with 22dbi antennas just a couple of feet away... It´s like staring into the sun. Ideal signal...

poli5681

Hi,

Maybe you could use something like this:

poli5681

Hi,

I presume you already opened the port at the firewall forwarding chain...

You have to add a "dstnat" Rule for your destination port 3389 at the NAT Tab and select action "dst-nat" and your internal IP as "to-address".

poli5681

No, its always better to use switching if possible, as long as you don´t need firewall rules etc. between the ports.
With switching enabled you always have wirespeed between the swiched ports;
Bridging takes some CPU-Power.

poli5681

Sorry Normis,

I thought it´s the same as with RB1100 - didn´t even check the product image

Anyway astude you can do your setup by binding 6-10 and 2 to the same bridge.

Edit.: It might be a better idea to use eg. port 10 for internet uplink. Gives you 1 more port for switching...

poli5681

Hi, RB1200 has 2 switch groups. 1st has ports 1-5; 2nd has 6-10. You can set 2-5 for switching (you did this already);Do the same for 6-10 and use port 6 as the master port. Now add a bridge and bind port 2 and 6; You won´t take advantage of the switch chip for traffic between group 1 and 2, but eve...

poli5681

Can anyone confirm the resolution of these issues? Which version of ROS resolves the issue or is it not out yet? We have a RB1100 we have taken out of service and would like to use it again. Rick Yes, i have a device in production now, after some testing with 4.17; Problems with Port 11-13 are gone...

poli5681

Maybe bridging ports 5 and 6, on different switch chips, would be even better?

Thank you RK; That might be even better.
I still have 1 RB1100 left to install; I´ll try and let you know my results.

poli5681

Hello NetworkPro,

I´ve ROS 4.16 and BL2.29 on my last RB1100 and ROS 4.11 and BL2.27 on my first;
So i guess all versions in between are affected.

Hello mihaialdea, I had similar problems with bridging and queues on my 1100s; I bridged Port 11-12 , enabled piping through fw, and added mangle rules and a complex queue tree for interface 12: The result was a more or less completely unresponsible RB - the interfaces showed only a few Mbps of data...

Hi, You have to add a network connection to the connection manager with manual IP and Gateway; Ubuntu disables the interface if it can´t find a DHCP Server and you don´t have a manual configuration. Default configured IP on RBs is 192.168.88.1; But it doesn´t really matter, because WinBox will find ...

Dear Martin, I´ve a few alu cases with RB800s installed here in Austria and the temperature is rising up 20C+ when exposed to direct sunlight - however they don´t fail.

Hi,

Anybody here using MT boards under high ambient temperatures? I´ve to build a few links in the UAE and i´m concerned about the high ambient temperatures and sun.

I usually prefer to mount them outdoors with aluminium cases, of course here in austria...;
Will they just work, or die?

Thanks.

poli5681

Yes - exactly.
You may find many threads here discussing the difference of such setups;
So you´ll get an idea what to expect of each one.

poli5681

The N cards have MIMO technology; This gives you better signal and higher data rates.
http://en.wikipedia.org/wiki/MIMO
But you´re fine with a single chain setup, even with N.

Normis had posted that 4.11 would fix this issue. However, there is nothing in the 4.11 release notes to indicate that this issue has actually been fixed.

Hi, If you need more than 100Mbit with POE your only option is RB800 with n-Wireless and a good dual-pol antenna. This is the only board to support 1Gbit Interfaces with ieee802.11af POE. Your costs might be a bit higher than 800€, but believe me, its worth. If 100Mbit are enough for you, RB433AH is...

Thank you. The link was up with 1Gbs and is now 100Mbit without autoneg and stable - didn´t see this. The routerboards IF was set to 100Mbits but synced with 1Gbs. Does the speed setting do anything, when autoneg is enabled? I´ll reenable autoneg, set the speed to 1Gbs (if that does anything) and wa...

Hello, You don need to use routes for this. Just configure one device as ap-bridge (or simply bridge) and the other as "station wds". Add a bridge and add the ether and wlan ports to that bridge on both devices. As long as your PCs are in the same subnet you should be able to do bandwidth ...
