[isalist] SBS 2000 + ISA serverHi Considering the amount of post regarding VPN through ISA, I thought that I would share my recent experience with the subject. I needed to configure an ESP tunnel from an outside router, to another router situated on a ISA DMZ. I configured standard packetfilters for UDP500 en IP protocol type 50. This didn`t work. What actually DID work, was enabling PPTP though ISA server ! I always thought PPTP was type 47 ? The tunnels went up and everything was fine. I should mention that ISA was patched to SP1, even though the release notes does not mention this issue.

I have two sites both with SBS 2000 installed, using all of the nice wizards provided by MS. Both networks are very simple, using a UK2net ISDN dial up account and an internal ISDN TA. Both systems have two matching 10\100 network cards, one connected, one spare for when (??) ADSL is available. Each server reports Unable to bind dial up packet filter, with the error 14121. Any initial ideas, more info can be given.
