How to set up rooting and masquerading in order to assign certain gateways to certain ports with assigned ip addresses in mikrotik?
Suppose, when accessing 192.168.1.1, the route was built through eth1 and some kind of 123.123.123.123, and when accessing 192.168.1.2 on eth2 and 124.124.124.124.
I ran into a problem that when grouping at the MasterPort level, only one incoming local address is obtained. Or is this built only through the association of local ports into a bridge?
