cPanel 'Sorry' page and 404 pages on recent WHM/cPanel install

Recently installed a WHM/cPanel on a home server installation WHM and cPanel are all behaving as expected but the cPanel sites won't resolve. The WHM/cPanel server is behind my PFsense box, I've opened the web ports and ports required by I ran cat /var/cpanel/cpnat [root@staging-server ~]# cat /var/cpanel/cpnat 192.168.1.251 80.229.15.223 The IP address internal is correct 192.168.1.251 The web-facing IP address is correct 80.229.15.223 Any ideas what the issue could be. Thanks
