I have a static IP package with my ISP and have my ClearOS home/office setup on one IP as well as a public-facing web server and a Nextcloud server. For security reasons, I would like to remove the internal connections to these servers and have all connectivity to them go through the WAN interface.

Currently, I can not connect to these servers via the wan interface. I am not sure if it is routing or firewall or both.

Any advice on altering the firewall and/or static routes would be greatly appreciated.

    What ports do you have open on your incoming firewall? You'll want 80, 81, and 443 for HTTP, Webconfig, and HTTPS access on the WAN side. If your server is in Standalone mode, you wouldn't have to worry about internal traffic. If it's in Gateway mode, you can use custom firewall rules to block LAN traffic.
