I moved into a new place with free internet. But they somehow restrict VoIP and games master servers, to where I cannot even connect to anything.

Quote :

Ventrillo is a type of VoIP service and is explicitly disallowed and not available on the Free & Basic Internet Service provided by DeNovo Media.

Anyone know if I can do anything to bypass this undetected?

you could try routing all your packets through an encrypted tunnel, but that's a waste of bandwidth...

Nothing you can do unless you have configuration control over both end points. ie your PC and whatever machine is at the other end (router, server etc). In that case it might be possible to set up a VPN. But given that they've gone to the trouble to block the services you've mentioned it's highly unlikely that they wouldn't have blocked any variation of tunneling protocol you might try using also.

In other words, you're pretty much stuck.
