tcp listening port help
hey Iím new to networking, and recently I installed azureus. it asks me to test a port for incoming peer connection, I have tried numerous port numbers and I am continually get a Nat error, I run Norton 2006 and also have an alpha shield.
I have two questions 1. is it necessary to have a tcp listening port to run this program? And 2. if so how do I go about opening a port?
