If you use iptables as firewall, add this rule:

/sbin/iptables -t nat -A PREROUTING -p tcp -s xxx.yyy.zzz.ttt --dport \
10022 -j DNAT --to-destination 192.168.0.10:22

the instruction -p tcp -s xxx.yyy.zzz.ttt is not necessary, it is only
if you allow a given machine to log on your gateway.

You can add in your .ssh/config file:

Host name-of-machine-behind-gw
        HostName  name-of-gateway
        HostKeyAlias name-of-machine-behind-gw
        Port 10022

and just type ssh me at name-of-machine-behind-gw
