I have a Comcast modem/router. I also have my personal router: Netgear R9000 — Nighthawk X10 AD7200 Smart WiFi Router which has Plex built into it. In order for my server to be Fully accessible outside my network, I have to put my Comcast modem/router in Bridge Mode. Is there another way to configure this so that I don’t have to put my Comcast modem in Bridge Mode?
Well it is possible that you can use some fairly complex port forwarding to get Plex to communicate with the outside world but it is not simple or obvious exactly what needs to be done.
Plex is designed to communicate with the outside world in a very specific way and it does not work well behind a double NAT situation or through most VPNs.
It is possible to get it to work the way you want but I am unsure if it would be worth the hassle. Why not just keep your modem in bridge mode? It is much easier that way.
Actually it’s not that complicated.
1 - port forward from your comcast modem to the specific IP your X10 has
2 - port forward from your X10 to your PMS server
3 - in Plex Web, set to manual and choose a public port (i.e. 50000)
comcast modem -> X10
1.2.3.4:50000 -> 192.168.1.50:50000 (IP given by the comcast modem)
X10
192.168.1.50:50000 -> 192.168.2.10:32400 (IP given by your X10)
