If you make Mikrotik Change the TCP MSS in PPTP/PPPoE servers it adds dynamic mangleing rules. They have action set to passthrough. If you add rule that have an action set to accept, and new client connects, then this client has an mangleing rule that cannot be proceed.
use action=passthrough, it keeps processing other rules in the chain after match.
ok… I have to make this:
If src-address is in range 192.168.0.0/16,169.254.0.0/16 then mark it in some flow, if other mark in another. It’s easy to be made with 4 mangling rules. But if I have a list of 1000 addresses than the CPU Usage can be dramaticly reduced with action=accept
