Norton “Internet Worm Protection”

Norton AntiVirus has this strange omission I just can’t figure out. For some reason “Internet Worm Protection” won’t allow for creating a connection to a PPTP VPN. Not very helpful if you have to connect to one of the many VPN’s out there that use this protocol.

First a little primer on making a PPTP connection . You essentially need two ports open, 1723/TCP, and IP Protocol 47 (GRE). Ok, this is pretty basic stuff. We can do that ;). Well in the little wizard Norton provides, to create a rule you have the following choices for protocol: TCP, UDP, TCP/UDP, ICMP, ICMPv6, All (pointless). No way to select GRE.

So the only way I’ve found to connect to a PPTP VPN thus far is simply to disable either just Internet Worm Protection, or disable Norton AV.

It’s rather odd that something like this is not supported. A search on Google didn’t turn up an answer. Symantec’s tech support database didn’t turn up anything helpful either.

I would have expected something like this to function without a hitch. I’m very surprised to see this requires any intervention, and even more surprised to see that even with intervention there’s still no way to get it working.
