Hm, with firmware 6.40.3 it started to work without any configuration change. I hate such experiments...

I have simple configuration, few VLANs and one trunk bridge with assigned trunk ports on CCR1036. If I configure CRS326 same way and connect it by its trunk port to one of CCR1036 trunk ports, I am not able (from CCR1036) to ping CRS236 management IP, I can not see it in Neighbours and it looks like...

To be honest, it will be very hard to do it, because we have around 200 devices spread all aroud our country, they are part of production system, they collect data and I can not afford to disable watchdog (watchdog pings one internal IP, visible only when VPN is up) at all of them and wait when exac...

We have noticed it with RB750UPr2 with firmwares from range 6.36, but we have replaced them by RB750Gr3, latest case was with RB750Gr3 with firmware 6.38.3 few days ago, which I have (after reconfiguration of L2TP client interface) upgraded to 6.38.7. If any other case occurs, I will let you know. T...

Hello, we use lot of Mikrotiks with USB dongle and L2TP VPN with watchdog resetting Mikrotik when VPN is not established. Sometimes it happens, that fully working Mikrotik suddenly disconnects and never connects back. In this case technicians take Mikrotik to me and when I connect Mikrotik to power ...

From yesterday conversation with support I select: Configuration should be changed to utilize switch chip features instead of cpu on this device. Most of CRS series devices are designed to be used as switches and cpu's are not that powerful and the moment it seems that there are some bottlenecks rea...

No word from Mikrotik support from 19.6.2015. All ports flapping on above mentioned Mikrotik router still continues.

What about current status of port flapping after few days? Is this problem solved by 6.30rc22?

On Friday Mikrotik support requested new supout.rif, because older one was not completely generated (I have generated it manually, but without any problem reported when I have generated it). No other info from Mikrotik except this request.

Yesterday I have sent this info to support - Ticket#2015061866000028 In log I can see all connected ports link down and up. On the other side of connected SFP links there are most of these down-ups also in the log. Some of them are not, so I think outages are so short that are not logged. down-up.png

From Mikrotik support page: Support Request Instructions When contacting us at support[at]mikrotik.com: Make sure that you have the latest version of the RouterOS. If you don't have it, upgrade your router to the latest version and check if the problem still persists! I administer around 200 Mikroti...

I had similar problem. Setup is like this: Application in internet sends every few second UDP packet with some data to WAN interface of Mikrotik. Mikrotik contains two NAT rules to dst-nat incoming packet to production and development servers in internal LAN. Only one NAT rule is enabled, so packets...

Normis, currently I am searching CCR offers of several main distributors in our country, there is NO word about "pre-production" status in their product descriptions. In this situation, in environment I manage, I can not afford to buy a toy which maybe turns into tool I need in unspecified...

I understand your point of view Dobby. I simply do not care whether this is first time when 64bit RouterOS is out. I am customer and I expect product to be functional without sticker "Tested on users", without waiting to next software releases again and again. I think Mikrotik tries to ent...

I have the same problem - RB1100AHx2 is unable to connect to DELL 8024 switch using ports 1-11. Finally I found, that the only port, which is capable to connect to this switch without any problems is port 12. Port 13 was not tested because it is occupied in production router. All other devices (serv...

This is what guy from Mikrotik support wrote to me (I suppose after he analyzed suppout.rif file): At one point l2TP server crashed. And left all addresses unremoved. We will try to repeat the problem and fix it in the future. But currently you can add a simple script in scheduler which removes all ...

I configured those VPN on new RB1100AHx2 as a replacement of old x86 based Mikrotik with ROS 3.17 where this configuration worked several years without any hitch, so my dissapointment is very strong. Instead fully functional router I have to scratch my left ear by right hand with the help of schedul...

Your problem seems to be similar to my: http://forum.mikrotik.com/viewtopic.php?f=2&t=65424 - looks like VPN servers are little bit screwed. There is also solution for recovery in my posts recommended by support.

Few minutes after my last post support sent me an answer to all my mails. Definively it is a bug in L2TP server. When L2TP server crashes, it does not delete assigned IP addresses so later it is not possible to complete connection because L2TP server is not able to insert internal IP into address li...

Still no answer from support after 6 days, I would like to work in such support... Today I noticed, that similar problem with not-deleted items in addresses exists also in Firewall-Mangle. My VPN connection change MSS and currently I have lot of mangle items in list. It seems that on VPN disconnecti...

Another newly created autosupout.rif file sent to support, still without answer. Hey Mikrotik, I am not some kind of fcuknig tester, I am your customer with routers in production environment!

Still no answer from support...

I would like to create script to remove all dynamic invalid IP addresses (problem described here: http://forum.mikrotik.com/viewtopic.php?f=2&t=65424 ) because I think this in the only solution for this Mikrotik bug. Without this script I am not able to reconnect my VPN tunnels when described pr...

Another info: when this problem occurs, all dynamic IP addresses of VPN interfaces are marked as "invalid" - so another solution is to manually remove all invalid addresses.

Brand new RB1100AHx2, about 50 L2TP tunnels, nothing nonstandard in configuration, after one day without any problem tunnels suddenly are not able to connect. Log from L2TP server: 07:39:45 l2tp,ppp,info tunnel6: terminating... - could not add address: already have such address (6) I have sent suppo...

What is the reason why do you not want to add static DNS entry?

What motherboard you use? I have had problems with MSI motherboard with VIA chipset when using RB44G - it was not even possible to login to Mikrotik 2.9.49 because Mikrotik freezed just after boot. I have solved it by installing Mikrotik and RB44G on other system (Dell Optiplex with Intel chipset). ...

My problem was not caused by upgrade to 2.9.49, network card RB 44G was not functional also in 2.9.46. Upgrade was performed intentionally in order to solve problem with RB 44G.

2 vlada1 - Routerboard has its own discussion forum here: http://forum.mikrotik.com/viewforum.php?f=3

Hi,
I have motherboard MSI N1996, DOM Mikrotik 2.9.49. Previously I have used 3x Intel Pro 1000 MT network cards without any problem. Now I bought RB 44G, replaced 2 Intel cards and after reboot Mikrotik freezes. Sometimes I am able to write down login name but that is all. Any suggestion?
