After configuring my Router OS 5.5 with a second internet connection and started using router marks to route traffic I am no longer able to connect from the outside in with winbox, i cant even get a ping reply, What type of rule do i need to make this happen?
PCC example in wiki describes what you need to do:
First it is necessary to manage connection initiated from outside - replies must leave via same interface (from same Public IP) request came. We will mark all new incoming connections, to remember what was the interface.
