Have you recently installed a firewall or changed any settings on your router?

You need to make sure VPN pass through (GRE) is enabled on the router.

I did recently (maybe) upgrade my norton internet security to 2012, but I cant find a VPN pass through option
That will probably be it.

Try disabling the firewall and then retest.
