I have setup an MPLS lab as shown here http://wiki.mikrotik.com/wiki/MPLS_Lab_Setup . I would like to know whether MPLS is working. When I ping from one router to another or across routers I don't see any traffic showing up on the MPLS "Forwarding Table". However, when I do a traceroute I ...

Is it possible to have an address list on a bridge firewall rule?

I have a client that has 70 branches VLANed into a single MikroTik bridge. They want to block all traffic between the VLANs except for PCs that end in in .12 as these should be able to video conference between them.

Hi Mojiro: Your Cacti scripts are simply awesome. Thanks so much for providing them to this forum. They couldn't be easier to use and I'm now monitoring over 700 items on my Cacti server. Do you know what I would have to do to show the "Simple Queue - Traffic" graph as bits/s instead of by...

Hi Mojiro:

Are these scripts the most current available? What version of Cacti do you recommend for running these scripts on? Will 0.8.7b work correctly?

I'm trying to automate getting a package onto a router using either fetc or /system upgrade and neither of them seem to work when embedded in an auto.rsc file or a plain script file.

You need to make sure the 532's have 2.9.5 running on them before attempting the upgrade...

Only 2.9.5, or anything above 2.9.5? The units were all 2.9.48 with Boot Loader 2.11 that I upgraded and they still bombed.

Ken

REDTDI

Yes they can be fixed with a Net Install. However the labour costs to getting a broken unit down fixed then back up a 300' tower in a Canadian winter is rediculus. I suppose we should have tested them ourselves but I did about 10 RB133s and RB150s without problems before I nuked the RB532s. I didn't...

We were having the exact same problems until I turned connection tracking off. Once connection tracking is off all of our problems disappear. If you turn off connection tracking while packets are being rejected the problem goes away, just as if you rebooted the router.

There are no batteries on RB500 series routers. You have to use NTP servers or else the clock is reset after every reboot.

The RB532 with 266MHz does about 50Mb/s throughput over wireless. We are changing some code to increase that. Over Ethernet, it can do 200-300Mb/s. I suggest that Xandar has the wrong information.
