I'm looking for info to publish a VPN server behind ISA 2004. When I set up a rule to publish, the VPN client sees the sever, but can not authenticate. The vendor tech support prefers a hardware based firewall. How can I get around this? The VPN server is Aruba Wireless. It allows remote Access Point anywhere on the Internet. The AP tunnels back using IPSec, NAT-T. TIA greg
