I think the main limiting factor is the RAM. It seems to start swapping to the flash, causing 100% CPU and lockup in 1-5 minutes. Installed on 112 and 133c. After 14 hours all work fine without remove any package... The throughput seems to be better than "old" 4.xx... more stable. Very ni...

Someone had tried to install Ros version 5.5 on rb 112 and 133?

There are problems, or work fine?

Thanks.

Flavioweb

are you expecting the router to receive one packet and send two? It does not create new packets, it only forwards them. You can only forward traffic to a single destination at a time. Or are you just trying to round robin the packets ? With "older" Ros3.0 if i set "To addresses"...

As i wrote here: http://forum.mikrotik.com/viewtopic.php?f=2&t=36663 i have a problem to forward ports to multiple IP addresses within a single rule.

'To addresses' should be '192.168.1.2', not '192.168.1.2/24'! Ok... But, with 3.xx the same port was forwarded from all addresses, with 4 no. And, again, what means the conversion from "192.168.1.2-254" to "192.168.1.2-0.0.0.254" automatically made by ros 4 in "To addresses...

With old 3.xx (and previous) to forward port 53280 to x.x.x.2 and x.x.x.3 simultaneously, i just used:

Action: dst-nat

With ros 4.xx is automatically converted to:

but... dont'work.

How can i achieve the result?

This post just to share my experience. Finally, today i have installed Ros 4 on my 2 routerboard,a rb112 and a rb 133c. It rock solid! Very much better than -old- 3.27 previously installed. Usually, with prevoius Ros versions, i must uninstall some packages to make the -system- fast and stable. This...

It's safe to upgrade rb 133 and 112 to ROS 4 and connect to an AP with 3.xx installed?

Can i have some problems doing this?

Just a question...how many people have been driving in a car and the car was hit by lightning? Or the car in front of you? Or next to you? Or going the other way?

No luck. Strictly science. If you are in your car, and a power line falls across it in a storm, what is the recommended course of action? DO NOT GET OUT! Do not complete any circuit to ground with your foot. The tires will insulate you. Rubber and air. Great insulators. In a car there the insulatio...

Mikrotik support and me, are trying to debug the "reboot kernel failure" that routerboard 133c (at least for me) show in the logs after every reboot. This -bug- are present from ros 3.10, and the last 3.11 don't resolve the problem. After an exchange of mail with mikrotik support, we need ...

Flavioweb

"rebooted because of kernel failure" is not a general bug, it's a system-specific problem. did you send a supout.rif to support? I already send a 3.10 supout file as showed here: http://forum.mikrotik.com/viewtopic.php?f=3&t=24422 and with me, also other people do the same. I recived ...

I believe if you upgrade the boot loader for RB100/RB500 series boards before updating the firmware to 3.10 it works effectively. I can't try if upgrade bios to 2.16 on rb133c BEFORE upgrade ROS to 3.10 will fix the problem but, AFTER bios upgrade with 3.10 already on RB, the "kernel failure&q...

Could you send the support output file after the kernel panic to support@mikrotik.com?

Latest working version was 3.9.

Why in "Connection Tracking" i have "Tcp Estabilished Timeout" = 23:00:00, but in "Firewall -> Connections" i have "4d 00:00:00" as Tcp Estabilished timeout?

Which MT OS ver you are using? Ver 3 have L-7 filter and with it you can use yahoo and msn Prioritization better.

How to?
Can you give and example?

Thanks.

I'm using ROS 3.3 on a RB133c, in "Connection tracking" there is a "TCP estabilished timeout" at "1d 00:00:00", and a "TCP Close timeout" at "00:00:10". It's a normal behaviour if some connections that move from "Estabilished" to "Clos...

I've just updated my rb133c to 3.0, using the information posted here.

From 2.9.49 to 2.9.50, then to 3.0 and all works fine.

Performance still the same as 2.9.49... No problem.

Only CPU percentage jump from 2-8% to 100% every few seconds, but pratically nothing change in normal usage.
