The problem was in a router after the mikrotik. It was blocking icmp packets.
Problem is now solved.

I'm implementing simple PCC from this manual - https://wiki.mikrotik.com/wiki/Manual:PCC 2 ISPs, and a script that should ping outside dns ( 8.8.8.8 ) for the sake of checking if ISP is working fine or have some troubles (lost packets > 50%) The problem is for some reason I can do this /ping 8.8.8.8...

Hello. Today I have found that excluding a server from being limited in a simple queue by moving it to the top does not work anymore. It worked as I remember on 5-th version of RouterOS. And it doesn't on v.6.29. Here is my config: 0 name="Main" target=192.168.1.0/24 parent=none packet-mar...

Hello, Dobby. Thank you for your quick response. Why this should be a problem? It is a point to point connection. It shouldn't be but I think it is the problem because of a several reasons: 1) my VPN connection can't establish reporting an error "809 - The network connection between your comput...

Hi. I'm trying to establish vpn connection to mikrotik, which is available from local network but completely unavailable from outside. The problem is in several wan interfaces (3 internet providers to be precise). From inside connections marked randomly, routing is marked, routing decision goes bril...

Did you try it without any mangle rules? Yes I did. The behavior is the same. The more I work with it the better I see the picture. I think that those ip packets come from established tcp connections. So after I switch ISP I need to reset all connections. Unfortunately for now I don't see other sol...

I've changed mangle rules to this ones: 0 chain=prerouting action=mark-routing new-routing-mark=Wan2 passthrough=no protocol=tcp dst-address-list=!wan1Mail in-interface=ether-local dst-port=25 1 chain=forward action=mark-connection new-connection-mark=Wan2 passthrough=yes connection-state=new in-int...

And one more. On interface ether-wan2 I see the same picture. Some of the traffic is trying to pass with src-ip from wan1 220.135.67.81. Do I really missing something?

Ok. Here is my "/ip firewall nat" 0 chain=srcnat action=masquerade out-interface=ether-wan1 1 chain=srcnat action=masquerade out-interface=ether-wan2 2 ;;; Mail server chain=dstnat action=dst-nat to-addresses=10.0.0.82 protocol=tcp in-interface=ether-wan2 dst-port=25,465,119 Here is my &qu...

Hi. I have 2 internet service providers. Lets call them "Main ISP" (wan1) and the second one "Backup ISP" (wan2). Every 1 minute my script checks connection of the main provider and if it fail the script changes routing rules by disabling one that passes all traffic through wan1 ...

Try to downgrade to 5.12 version.
My router started to show the same simptoms after upgrading it to the 5.14 version.
See my comments on http://forum.mikrotik.com/viewtopic.php ... 25#p309713

Sound's like I have friends to share the misfortune - http://forum.mikrotik.com/viewtopic.php?f=13&t=60521

was it available by MAC address, Telnet, SSH or any other method, or you just tried winbox? It would be great if you tried and let us know more details. Could it be pinged? I've tried to get to the router by MAC (using winbox). Without success. Have tried to scan network for present any mikrotik de...

I have some strange router hanging on boot process. Link on ethernet1 is active and still, but no lights on others links. And router is not available by winbox. After downgrading to v.5.12 everything was fine. I've checked this twice (upgrade, reboot, downgrade). Every time the same result. Router R...

RB1100AHx2, v.5.14. The same problem. 5 ip addresses on outbound interface and no reaction on src-address parameter at ping command. If it still is the issue, maybe that's not a bug, maybe that's a feature? :) Are there some ways to set distance on automatically created routing rules? Does anyone kn...
