For complete details on setting up VPNs through ISA, see:

http://www.isaserver.org/articles_tutorials/topic/configuration_security/

which is Tom Schindler's excellent ISA site, and do a search for "vpn" in the configuration_security tutorials.........

Let ISA do it for you, from the MMC.  Right Click the Network Configuration icon and say Allow VPN connections.  It will then setup RRAS for you and put in the necessary packet filters.  You may need to tinker with RRAS a little afterwords

OK, that's the right answer.

To complete this :

VPN/IPSEC : UDP 500
VPN/L2TP : UDP 1701
VPN/PPTP : TCP 1723

Good day !
