Actually, it's not a network problem.
There's several issues going on with his server, as it's a custom modified installation of Redhat 7.3 with a serious Ensim flair. All packages were coded to be integrated with Ensim. My team and I had to completely uninstall and reinstall Apache and PHP, as well as an RPM package of MySQL. The Kernel was unstable, as well.
The good news is that his issues are now resolved and his server, though still not quite up to par to our standards, is very stabilized and operational.
macker123, thank you for trusting Thomas and myself with your server, it was truly a pleasure working with you.
