Outside network access

i have looked at the other similar threads who had this same issue but i also have the problem of not being able to access my ubooquity server outside my home network.

i am using an Asus RT-N66U router and a Zoom cable modem. The Zoom is strictly only a cable modem so there are no settings to configure when i log into it. i have forwarded my ports as instructed from the portforward.com page for my particular modem. i have also added an inbound exception to my Windows 10 firewall for port 2202. im no network expert so im just following guides i find on the internet to the best of my knowledge. i still cannot connect outside my network.

i run a Plex server and don't recall having to do anything special w/ it when i installed it. there was a popup box asking to add it as a firewall exception, i said Yes, and after that it just worked. so im really stumped as to why my set up is still not working despite following guides and the other threads here.

one thing im not sure how to do that was mentioned was "adding Java JRE" to my firewall exception list. i have no idea how to do that. i see Java(TM) Platform SE Binary in my Inbound rules so i thought that was enough?

please help!
