I just installed Suse 10.1 on two machines on the same LAN. I can SSH between the two machines on the same LAN just fine. However, I can not SSH to either machine from outside my router (WAN). Something must tell the SSH daemon to accept only local connections but not WAN connections.

The problem is not with the router/firewall. I've temporarily named one of the machines as a "pass through" on the firewall, so any and all packets are forwarded to this machine.

Do I need to make an entry in a file such as /etc/hosts.allow or some other SSHD config file to allow remote logins?
