I am running Exchange 2000 Ent. on two backend servers and have a front-end server as well. My PIX firewall has a static NAT that forwards traffic from the outside to my OWA server which is on my LAN. Accessing the OWA server works outside the firewall. However, OWA does not work internally except to enter in ip_address/exchange. I thought about creating a CNAME record on my DNS server to resolve my OWA server URL except my internal AD domain name is different than my public domain name. Is there a way to create a rule in my firewall that will redirect to my internal OWA server?
