Err... you need an IP number and possibly a port number after the
'fwd', which is what the 'next hop' address is set to for packets that
match the rest of the line:
ipfw add fwd 123.45.67.89 tcp from 65.xxx.zzz.yyy to 192.168.0.5 port
Note that the packet itself isn't rewritten at all, so you will have
to put in place something on the destination machine to accept
packets destined the original address.
Cheers,
Matthew
