I’m using RouterOS 6.19 x86 on Virtualbox+GNS3 sim.
There are 2 virtual WANs in my test environment. I use PCC manual to make them work.
After route switching existing connections are using old WAN IP on new output interface. I decided to mark such connections as “bad” and clear them periodically.
Everything is OK with TCP and UDP connections. But ICMP connections cannot be deleted. Even when I try to remove it manually through winbox or console, I receive error 6:
[admin@nov] > ip firewall connection print
