iptables port forwarding

I'm trying to configure IPTABLES to change outbound traffic from to to and then when replies on 6060, convert them back to 5060. I will need to NAT the address to a public IP on the host running tables (I will use as the external on the tables machine). This is VoIP so I will also need to allow UDP for RTP to/from the two hosts involved in the session. A complete session might look like this:

TCP -> translated to -> -> translated to ->

No UDP ports need to be translated but the UDP traffic does need to be natted to/from the public ip on in/outbound traffic to/from

Any help is appreciated.
