Hello,
I’ll try more simplify my setup and please for help.
On router:
Eth1 192.168.1.1/24, reachable 192.168.1.0/24
Eth2 192.268.2.1/24, reachable 192.168.2.0/24
On device1 (192.168.1.10) conected on ether1 need reach device2 (192.168.2.10) conected to ether2. But without setup route on both devices (both devices have 0.0.0.0/0 setup to another “Black hole”). I cannot setup end devices, only Mikrotik between them.
So, need from 192.168.1.10 “ping” to fictional address 192.168.1.100 (need to go packet to Mikrotik) and dst nat destination address to 192.168.2.10 (need go out from ether2 to device2) and also src nat source address to 192.168.2.1 (need say device2 to reply back to Mikrotik). On back way need translate back - src from 192.168.2.10 to 192.168.1.100 and dst from 192.168.2.1 to 192.168.1.10.
I think I need do both src and dst nat on Mikrotik.
Thank you
Rob
