Your laptop on 192.168.33.10 is receiving which ip as default gateway from DHCP server? It must be 192.168.33.1 (mk eth3 ip address as you said). I suppose you trying to ping 192.168.0.x from it, right? Think the problem is yours networks don't know the path to reach each other. Try to do some trace...

hello, If you are using winbox check under Wireless -> interface, then select the wireless interface e take a look on datarates, if its not on dafult try to use it.

Hola, In my opinion routing is better than nating at 90% of cases. In your case think the best choice is avoid nat because you can do all the filter on mikrotik and keep resources of your mikrotik box for queues and other jobs. Splitting /24 you will have the following subnets: 79.28.22.0/30 (as u s...

Hi rock! I have a simlilar configuration here, think the major difference is I'm using two boards. As said before, my setup has two RB1000 and I have one BGP session established with my ISP on each board. Then, to use only one link I'm sending different a greater matric on my backup session. At the ...

I know its happens because of the number of routes r...

Hi Mike,

Are you using winbox to do the configurations? If you are new on Mk world try to do basic configurations using it. You
can easy add static IP address or create static routes using that interface. Once you did it, open a CLI and see what
winbox did for you.

If u want to set IP address when your mikrotik is doing src-nat u need to use a src-nat rule and not a masquerade one. Use something like this: /ip firewall nat chain=srcnat out-interface=<out ineterface> src-address=<your local net> action=src-nat to-address=<ip on out interface> You must have IP a...

Changed tunnel mtu to 1500, same result!

And... packets bigger than 1476 not supposed to be fragmented?

Hi, Recently when testing a tunnel connection between a FreeBSD box and a Mikrotik RB1000 ROS 3.26 I found a problem with 1500 unit packets, packets with this size can't pass thru tunnel, any other with smaller size can pass without any problem. My tunnel configuration is: freebsd: sbin/ifconfig gif...

uldis,

I can do it now because all my RB1000 are in production (using 3.27). But it happened right after was created the first mr. I got a new card, put 3.28 and
created a MetaRouter.

thiele

Hi,

Just experienced that problem, after upgraded my RB1000 to 3.28 the board dont stop restarting! I tryed with a zero config board with 3.28 too and when
I create a metarouter board reboots and keep booting forever. Tested on two boards!

Hi, Look at your second screenshot, specially to selected route. You really need it? 192.168.1.0/24 is not connected to your board (DAC just after selected one)?

You need something like this to map port on your external IP: /ip filrewall nat add action=dst-nat chain=dstnat disabled=no dst-address=<your external ip> dst-port=7777 in-interface=<external interface> protocol=<tcp or udp> to-addresses=<your internal ip> to-ports=7777 Jorge

Can you post your firewall rules? at least forward and nat.

thiele

What is your hardware? Maybe your new problem is related with CPU Load. Look under system -> resources.

Hi, I think you are receiving bgp routes with wrong next hop address. You have two options to solve this problem. 1 - if you have access to cisco, try to force next-hop and/or look if your update-source is loopback. 2 - you can make a input filter that foce next-hop to correct IP. I recommend the 1s...

Hi It occour because you are doing NAT on you mikrotik, check it out and look if you really need to do it at mikrotik.

Well, I supose you are using bridge onr you setup. If it is what you trying to do I think the better
way to do is using WDS and adding ports to the bridge. Look this howto

and check your conf.

Hi Sergio,

I think your problem is related with MTU size. If you search at google you will see some
users getting problems with DSL PPPoE connections and in major cases the problem was
MTU size, see this post:

Hi bejcd, What exaclty you do when take mikrotik out and put alvarion? Alvarion is using the same antenna and cable or are they using integrated panels? Its important to know that to start debuging the problem. If antennas are the same it can indicate a card problem. If not check if cables are ok an...

Hi bochin, I think you need to know if the problem is not traffic, high latency can indicate too many traffic on your link or too low bandwidth avaliable, so check it first (traffic, CCQ and throughput). Well, about the power... how is link signal str? In my opinion you will get a more efficient lin...

Hi, Looking at your net layout, looks like NAT is only made on your adsl modem, right? If its true, you dont need to set any port forward on your mikrotik, you need to put a static route on your modem when destination is 192.168.1.0 use gateway 192.168.10.254 and make sure you mikrotik is just routi...

thiele

Hi,

Maybe the problem is the size of packets you are using on your tests.
Try to use smaller packets, like 1440 or something like that.

thiele

How about the signal, CCQ and traffic? This response time can indicate high traffic or a low link throughput. If your problem is the throughput you may need to take a look on your radio cards or if the problem occour in other channels. Are you using 1W and 600mW cards for 1Km range link? I think you...

thiele

Hey,

I recomend use of 5Ghz (802.11a) cards, like R52 or SR5.

There are more powerfull cards, like R52H or XR5 but you dont need them for a 7Km link.

Right configured this hardware will offer something like 25Mbps aggregated or more.
