SSL IIS 6.0 - Cannot reach site from the outside


We have a website using verisign using SSL on IIS 6.0 with firewall off. I am unable to reach the site from the outside (HTTPS://) but I can reach it from the inside using HTTPS://

I ran a port scan from the outside and it is listening on Port 443.

Any reason why I cant reach the site from the outside based on this basic information?

Basicly you do Telnet with your Public ip.

and then you check with your router if ip is forwarding to correct Machine.

and also how did you set up SSL, with "www" or without "www". that also matters.
Saqib KhanSenior DeveloperCommented:
Try the Following.

Make sure in IIS you  have specified port 443 under site properties
if using windows firewall or any other make sure 443 is open for Server
try to do a Telnet from outside, if you can connect to HTTPS port.
in command do following
telnet <Server IP/Domain> 443

if you see a blank screen that means 443 is open to public then your network settings are good, but if you dont see a blank screen then your port is not opening/exposing to the public.

I telnet from the outside and a blank screen comes up.
The IIS property setting are specified for port 443.

How can I tell if the public IP is mapped to the internal IP?
