i've tried several times, using multiple different rules i've found from
different sites, and i still can't get port forwarding working. does anyone
have working rules they could send me? i'm trying to forward packets from my
isp to port 2222 to an internal ip (i use nat) and port 22.

any help is much appreciated! this has been driving me crazy. 8)

There's this rather cute rules I dreamed up August last year when I wanted to transparently direct traffic headed to RH to a site on my LAN: iptables -t nat --src --destination ftp.redhat.com -A PREROUTING -i eth1 --protocol tcp --dport 80 -j DNAT --to-destination

and these two to forward incoming VNC connexions:
iptables -t nat --src -A PREROUTING -i ppp0 -p tcp --dport 5901 -j DNAT --to-destination iptables -t nat --src -A PREROUTING -i ppp0 -p tcp --dport 5801 -j DNAT --to-destination
I guess those are pretty much what you want.
