forwarding ssh requests

[Thomas Cameron]

That's what I was going to answer, but I am not getting it to work...

[root@mailtest1 root]# iptables -t nat -A PREROUTING -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
ssh: connect to host 127.0.0.1 port 3022: Connection refused

I have tried to DNAT to a local address as well as another address with the
same results.

What gives?
