Advanced Policy Firewall localhost forwarding

I am semi-familiar with advanced policy firewall (APF) routing chains, however I am having issues writing a rule to forward port localhost:139 to 10.0.0.1:139

I'm not sure where to put it. In the preroute, or postroute file?

I basically want something like:

$IPT -t nat [output?] -p tcp --dport 139 -d 127.0.0.1 -j DNAT --to-destination 10.0.0.1:139

Any advice?

Thanks!!

#iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 25 -j REDIRECT --to-port 2525

I'm using APF, which is a configuration script for iptables, your examples don't work unfortunately.

$IPT -t nat -A PREROUTING -p tcp --dport 139 -i lo -j DNAT --to-destination 10.0.0.1:139

Ok after a lot of reading and such, I've discovered that this line of thinking is ridiculous. Although it seems "so simple" of an idea, it just isn't.

I've gone the SSH local to remote forwarding route:

Generating an SSH key with openssh, so I can login to localhost without a password, then using screen to forward my ports (so I can close the console window), and will have to use netcat to forward my UDP ports.

Thanks for the help.

I'll give you the points just because you tried!!
