Virgin blocking Microsoft PPTP VPN?

May 17, 2010 2 comments

Interesting….

I’ve recently continued having problems with my Wife’s VPN, using PPTP VPN (the one you use by default in Windows). Rather than timing out during authentication, which was what I was getting when the router seemed to be blocking it, these days it seems to be rejecting it immediately. I’ve tried enabling VPN passthrough on my DD-WRT (ex-Virgin) router, and even connecting directly to the cable modem with no router, but I still get the same problem.

Then, occasionally, it works.

However, the interesting thing, is that the IT Admin for her work (a large UK university) says he’s had 4-5 other people also having this problem – all Virgin customers.

I doubt they’re deliberately blocking it – but perhaps something in their configuration isn’t letting PPTP through?
