Server port forwarding completely broken

[Opticulex]

I've been attempting to debug this for like 2 hours (assuming a code error caused by v2.1.0) and finally figured out the cause.

A few days ago I switched routers to a newer and 3x faster model. After the server switched over, port forwarding is broken. While Port 80 is configured open for inbound requests correctly, it doesn't work for some bizarre reason. You can try this out by visiting ITFautoupdate.txt and attempting to access the Server Public IP address in your browser. If it doesn't work, the server is down by either the server or router's fault.

This is hopefully a simple fix or there might be a major problem. Either the router is completely broken for port forwarding, a router or server firewall is incorrectly configured or I screwed up somewhere during configuration (hopefully the latter).
