I would like to know how to confiure my network to get a SAN name to work on my network. I have an SSL for our Exchange server at address mail.mydomain.com and it has been working properly the whole time. I needed to get an additional SSL for a web application for mobile devices. I created a SAN on our current SSL and it is web.mydomain.com. I went to our domain registrar and created a DNS entry pointing to a public address which is NAT'ed to an address on our LAN. The ports for the Web address have been opened however the port is 3443 instead of 443. When I try to go to that address the address does not resolve to port 3443 and when I manually put the port in the certificate comes back stating "None of the common names in the certificate match the name that was entered (web.mydomain.com)" What am I missing? Do I need to make an entry on my DNS server for my domain? Do I need to make a modification on my registrar DNS?
