Port forward to web server

peter zaher

I have Website published on IIS as http on port 8888.

I added it as Web Server and created business role add authentication method.

I can access the website on new port 8887 from Lan, when i tried to access the website using Public ip from wan didn't worked.

I tried to create DNAT for the new port but still face the same problem.

 

Regards,

Peter Zaher

    Hi Peter, 

    As per the logs you have posted, could you verify the WAN port is Port1 or 2. Also, the request came from the LAN users, could you elaborate the issue while connecting from WAN or from LAN?

    If the connection is from LAN and if the server is in DMZ zone, could you check if there is a LAN to DMZ rule?

    HI Peter

    Got it , Is there a LAN to LAN rule with NAT applied? I suspect that the local loopback rule is missing.
