I have an application, OWA, running on a SBS 4.0, I run NAT with a Cisco router managed by the T1 provider. I have the internal application assigned to 10.0.0.x and the router mapped public to this private IP. Cannot see the application from the web- the private and public IP addresses both ping - but cannot telnet to the private #. I have added the private IP to the WAN NIC card addresses- what did I miss?
