Yes. You can do port forwarding/redirection. Is your firewall running
a 2.4 kernel? If so then you want something similar to the following:
/sbin/iptables -t nat -A PREROUTING -p tcp -d <external interface IP> --dport 5555 -j DNAT --to-destination <machine to forard to>:22
/sbin/iptables -I FORWARD -p TCP -d <machine to forward to>/255.255.255.255 --dport 5555 -j ACCEPT
Change IPs and port to suit setup.
Then you run: "ssh -p 5555 <external interface IP>" when connecting from
outside. Note there are security implications to this, allowing access
to a machine inside your network...
