We have a small network sitting behind a CISCO 837 DSL router. Thre are two servers sitting in the local intranet. And I do port redirection on the router.
Server(IP# nnn.nnn.nnn.16) runs a web based application (IIS on Windows 2003) and I can access it from outside of the company network.
I have Exchange on another Windows 2003 box (IP# nnn.nnn.nnn.15) and I have configued OWA on it. I can run OWA within the company network. But I can not access OWA from outside of the company network. (when I do an https://.., receives Page Not Found). I have created the required certificate (for SSL) through Windows 2003 CA.
Below are the port redirections I have configured into the CISCO 837 router:
ip nat inside source list 102 interface Dialer1 overload
ip nat inside source static tcp nnn.nnn.nnn.15 443 interface Dialer1 443
ip nat inside source static tcp nnn.nnn.nnn.16 80 interface Dialer1 80
access-list 102 permit ip nnn.nnn.nnn.0 0.0.0.255 any
What am I missing?
