I can use SSH from client to gateway server and from client to client, but I can't access clients from gateway server by SSH. Anyone can give some advices? Thank you very much.
You have to make a packetfilter rule to allow it from the gateway to the client. You can't do ssh from the Firewall per default. Just take as source the Firewall interface ip your walking out, and either as destination any or the targeted client.
