[c-nsp] ios fw & pptp & 12.4(17.8)T

[matthew zeier]

Before I go crying to TAC, I'll try here first -

I upgraded a 3845 to 12.4(17.8)T and ever since folks using PPTP 
complain that they can't connect to outside PPTP servers.

I don't think I'm doing anything esoteric - I have an inbound ACL with a 
default 'deny ip any any log', ip inspect on, nothing in the logs.

I ruled out the computers themselves - they work fine on networks not 
behind this router.
