Same problem, mostly.
Installed the new 6.0.? version. Went to dial the internet, using netzero. It dials, says connection, says I'm logged in, sits there for 2 minutes then decides the connection isnt working and tries to redial. Wont log on fully with wingate running.
Turned of wingate. COnnected to the internet. Loaded webpages fine. Turned wingate back on, internet connection stopped responding.
Tried turning off my network adapter for the internet network. Internet connects and works fine. TUrned the adapter back on, internet stops responding. I have checked and have wingate set to use the dialup for internet traffic... it knows the internal network leads no-where. Yet whenever the internal network is enabled and wingate is on the internet goes dead.
