Incoming Connetion - What port used?

[Andy]

Hello,

If I am trying to get my Windows XP computer to accept
incoming connections using TCP/IP, what ports will I have
to open on my router to be able to connect? Thanks!

You only need port forwarding setting up for the ports where you actually
need to accept incoming connections from the internet.
If your pc runs a game server, for example, and you obtain the information
that the game listens on port 23323 then you'd set up a router rule to
forward TCP and/or UDP at port 23323 to your machine IP address 192.168.0.2
(if that were your ip address). If you wanted all traffic to be forwarded to
your pc then you'd set up the router DMZ to your IP address, but that's
dangerous.

Yes, I realize that... for instance, my router forwards
port 3389 to my computer, as 3389 is the port used for the
windows XP Remote Desktop connection. When I talk
about "incoming connections" I don't mean any Ip traffic
that hits my router. I am talking about the "Accept
incoming connections" option that you can run from the
network connections setup wizard. What port does that
program listen on? Thanks much for your help though.

Connections in the connections folder add new IP interfaces that have their
own full set of ports.

I would assume you would be using a PPTP based VPN, which operates on
TCP 1723 and requires GRE Passthrough (aka PPTP Passthroug/IP Protocol
47).
