This as got me completely stumped.

I've checked my firewall settings, googled till I've almost cried and cant figure it out.

Reinstalled ET completely from scratch after deleting all files, tried ET:Legacy, same problem except it finds 500 odd servers but keeps telling me to check filters. 0 of xxx displayed.

I am unable to join any servers using the +connect command line.

It was working fine till last weekend then it dropped all the 'net side of things'

Any suggestions?
