Hello:

I have a webserver with a public IP address on one interface, local network on another

I have an rtsp server on an internal network

I want to set up port forwarding so that any requests for an rtsp stream arriving at the public address get sent to the rtsp server, so that I only need a single public address.

My attempts to configure iptables to date have failed - can anyone give me any advice on this?

Cheers,

Ben
