I need to forward all connection to any address port 22 to a different gateway (i.e. no default). Firstly I suppose to do it with ipfw:

sudo ipfw add 5 fwd $EXTERNAL_IP,22 tcp from any to any 22 keep-state

But with Mac OS X Lion it seems do not work. Anyway, looking at ipfw documentation I see it is deprecated and I should use pfctl.

So I have modified /etc/pf.conf file:

rdr proto tcp from $internal_ip to any port 22 -> $external_ip port 22

But with no luck.

Does anyone know how to translate or forward all connections generated by local applications to any address but port 22 to a different gateway/ip address?
