IPtables port forwarding question

[calimero1505]

Hi all,

We use IPtables portforwarding so we can use port 80 as listening port and not use root as stream owner.

The command we use is:

iptables -t nat -A PREROUTING -p tcp -d our_ip --dport 80 -j DNAT --to-destination our_ip:4000

Now we have follwing questions:

• 1) The shoutcast directory does route the streams to port 4000 in this example. Offcourse this is the normal behaviour, but is it possible to let it point to port 80 also?
  
  2) The streamsource needs to connect to port 4000. Is it possible to make it connect to port 80 also, so the source can skip other ports then port 80 also?

Hope my questions are clear.

Thanks

J.J.
