ISA server not relaying clients IP to web server.

Hello everyone,
I am hosting a website on the same machine as my ISA server. The reason
for this is that my isa server is acting as a gateway for a wireless
hotspot - users are redirected to my site, where they sign up and get a
VPN client login, and are then able to connect to the internet. This is
all working fine.

However, I need to know what thier IP address is.
When they connect to the web application (written in ASP) thier Ip address
always appears to be coming from the isa server itself, and not the
clients IP. The clients IP is completely masked by the NAT firewall

(for those of you who are familiar with asp, the
server.requestvariables("CLIENT_IP") and "REMOTE_ADDR" and
"HTTP_X_FORWARDED_FOR" all return the address of the ISA server, not the
client)

Is there any way i could fix things so that the clients IP will actually
be forwarded in the environment variables?

Thanks folks

Matthew Dendle
