Recently I came across an issue in SharePoint.
Environment:
1. A server with static IP Address : (14.*.*.*). This is the server that is public facing.
2. SharePoint Server with IP Addres : (10.1.1.55). This is an internal IP within intranet.
Now I wanted to make the SharePoint Site at http://10.1.1.55/ accessible outside intranet using Port forwarding.
Initially I pointed http://14.*.*.*:8082 to http://10.1.1.55/. But this didn’t work out because when I entered http://14.*.*.*:8082 in browser the port 8082 changed to port 80 and hence page couldn’t be found.
Solution:After trying for long I figured out that port forwarding should use same port internally and externally.
