Ever since I installed a router I cannot use Kazaa or any other P2P software
anymore. The problem is that the Kazaa client on my PC cannot make a
connection to the Kazaa network. The same issue with Warez...

I am using all other applications that make use of internet access
successfully and I am not using a firewall or anything similar, so this has
to be a piece of configuration that needs to be changed somewhere. Anyone
knows what I should do?
