forwarding ssh requests

[Thomas Cameron]

Never mind, I got it to work like so:

[root@mailtest1 root]# iptables -t nat -A OUTPUT -p tcp -d 127.0.0.1 --dport
3022 -j DNAT --to-destination 127.0.0.1:22
[root@mailtest1 root]# ssh 127.0.0.1 -p 3022
root@127.0.0.1's password:
Last login: Tue May 20 14:09:45 2003 from localhost.localdomain

Don't understand why it works on the OUTPUT chain but not PREROUTING, tho.
