SSH access to default Gateway (Mikrotik) thru secondary gateway (non Mikrotik) port forwarding

Hi,

i’m a novice in Mikrotik router configuration, i need to access my Mikrotik default Gateway, using SSH thru another router with 22 port forwarding. Mikrotik (default gateway) and Fritz (secondary gateway are both connected in LAN.

Port forwarding works but i think that replay to the traffic goes to default gateway and not to secondary,

Someone has a solution?

Thanks a lot
