I have ISA 2000 connected to a public network, with a private subnet of 192.168.0.x and a Screened Subnet (DMZ) on the 172.16.x.x range. My web server is 172.16.96.2 and the DMZ interface on the ISA server is 172.16.96.1. I have done the following in attempts to publish this server to the external interface, but to no avail: - Enabled listener on port 80 for public interface. - Everything listed in MS article Q313562. - Made sure the public DNS record is pointing to the IP of the external (public) interface on the ISA server. Nothins seems to work. I can however access the web server from the private network using both it's public FQDN and using the external IP address. I am using only the ISP's DNS and the FQDN of the web server is resolving properly. Traffic just doesn't want to pass from the public network. I've even tried using a web publishing rule, even though the Q article above makes no reference to it because the web server is on the perimeter network. Please help?
