May 28, 20206 yr Hi, I have installed Mikrotik CHR as VM on unraid. My configuration looks like on the attached image. I am experiencing networking problem. When I am logging in to the dude server using dude program it say "getting stuff" at the bottom. During this stage latency to my mikrotik VM jumps above 100 ms, like that: Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time<1ms TTL=64 Reply from 10.1.1.230: bytes=32 time=102ms TTL=64 Reply from 10.1.1.230: bytes=32 time=274ms TTL=64 Reply from 10.1.1.230: bytes=32 time=113ms TTL=64 Reply from 10.1.1.230: bytes=32 time=93ms TTL=64 Reply from 10.1.1.230: bytes=32 time=77ms TTL=64 Reply from 10.1.1.230: bytes=32 time=53ms TTL=64 Reply from 10.1.1.230: bytes=32 time=22ms TTL=64 Reply from 10.1.1.230: bytes=32 time=12ms TTL=64 Reply from 10.1.1.230: bytes=32 time=115ms TTL=64 Reply from 10.1.1.230: bytes=32 time=102ms TTL=64 What can be causing the problem? I have tested with one cpu, two cpus and all cpus passed to vm. Edited May 28, 20206 yr by Kacper
May 29, 20206 yr Hey Mate, Edit: all good figured it out will see if i have same issue with dude Don't have an answer to your question but i am interested in how you got your bridge interface to show up on the mikrotik? Edited May 29, 20206 yr by Draco
May 29, 20206 yr Author I have installed Mikrotik CHR version with VM setting as in my first post. What is amazing is that Mikrotik gives CHR version for free!!
May 29, 20206 yr Author Is it possible to install some app/plugin to get more qemu options to configure? I dont see howto create second network interface in unraid for instance.
June 2, 20206 yr Author I have found the answere. Mikrotik CHR free version has bandwidth limit on single interface 1Mbit. Dude is using ping to probe latency, so every logging in to dude server causes traffic that will make false reading for dude ping probe, as it wil overfill bandwidth. To solve this problem following rules can by applied in the mikrotik terminal: /ip firewall mangle add action=mark-packet chain=postrouting new-packet-mark=OUT passthrough=yes protocol=tcp add action=mark-packet chain=prerouting new-packet-mark=IN passthrough=yes protocol=tcp add action=mark-packet chain=prerouting new-packet-mark=IN passthrough=yes protocol=udp add action=mark-packet chain=postrouting new-packet-mark=OUT passthrough=yes protocol=udp /queue simple add max-limit=900k/900k name=OUT packet-marks=OUT target="" add max-limit=900k/900k name=IN packet-marks=IN target="" This will limit maximum bandwith usage and prevent latency to go high. Now dude server will work unjamed. Otherwise one can get P1 license, then the speed limit is 1Gbit, but it will hit the same problem at 1Gbit connection So rules presented here are also aplicable for 1Gbit interface, but instead of k one can put M for Meg. SOLVED!
