I'm sorry if this comes off as long-winded but I'm not very tech savvy LOL but here goes...
So today I upgraded to Xfinity gigabit service so they switched out my old modem/router for a new one(TG3482G) of course well I have a Plex server that I use all the time, so after the technician left I went to run my Plex then I noticed the "not available outside of your area" message and prior to that I wasn't having any issues with it. So I began the procedure of troubleshooting my issue, I followed exactly what the Plex thread suggested I made sure that UPnP what's enable and it is, I made sure the firewall was not affecting anything ect ect so I finally gave up and just decided to try the port forwarding option I went to the Gateway I then went to Advanced section which sent me to internet.xfinity.com I then went to port forwarding section and I went through the list of devices and I don't see my Plex server anywhere! and they don't give me the option to manually input the devices that I want port forward. I know it used to give you the option to manually input everything but it doesn't anymore for some reason. I'm just stuck and frustrated and I was wondering if someone would help me fix this problem i would greatly appreciate it
Sorry for the issues you're running into. If you follow the steps provided below, are you able to manually enter devices this way?
