ActionScript socket port

Hi,
I use ActionScript code to communicate with TCP server (that I wrote in .Net)
_global.socket = new XMLSocket();
_global.socket.connect(IP, port);
I use port = 13000.
Everything works fine.
But in some other computers, I cannot achieve connection.
I suppose it is because of firewalls.. that "block" this port. Right?
Can you suggest me other port number to use such that I will not have this problem?
Notice that I already use at the server (listening) side the ports 80 and 443.
Thanks, Aryeh.

Hi, unfortunately what port is available will always depend on the network of the client.
I don't think it's possible to say port xyz will definately be made available.

i think you might be able to do something with C# where you can check if a port is available if not go find another one.
but i'm not sure, you'll need to ask the C# guys.

Hi blue-genie. after all maybe your idea is good.
I should go to the "problematic client" and search for a port number that works for me.
unfortunately, there are technical and anministrative difficultied to test it.
I hoped that there is some "table" of ports un-blocked by common firewalls,
and someone that can advice which to use.
Thanks, Aryeh.

sorry can't help you with that.
on our networks and my clients, generally all ports are closed except 80 and 8080 unless explicity open.

thx blue-genie (sorry for the delay I was expecting other solution)
so in that case I'll try 8080...
I'll let you know if it works.

actualy you gave the solution! Thanks blue-genie.
http://www.grc.com/port_8080.htm
says:
port 8080 is a popular alternative to port 80 for offering web services. "8080" was chosen since it is "two 80's", and also because it is above the restricted well known service port range (ports 1-1023).

Its use in a URL requires an explicit "default port override" to request a web browser to connect to port 8080 rather than the http default of port 80.
