I recently upgraded my router (from an ASUS RT-88U to an ASUS GT-AX11000) and had to enable port forwarding on the router (port 32400). However, I cannot connect to the Plex Media Server now, unless Comodo is turned off. ALL of the PLEX executables are allowed and PLEX is set as a TRUSTED vendor.
I have also disabled all of the (Firewall) ADVANCED options (Filter Loopback, Block Fragmented, etc).
Windows Firewall has no effect on or off - only Comodo.
You may need to port forward more than just that one port.
TCP port 32400 for the Plex Media Server.
UDP port 1900 for the Plex DLNA Server.
TCP port 3005 for Plex Companion.
UDP port 5353 for network discovery.
TCP port 8324 for Roku via Plex Companion.
UDP port 32410, 32412, 32413, 32414 for network discovery.
TCP port 32469 for the Plex DLNA Server.
Nope, no luck - added every single one of them to the router and still it will not connect with Comodo enabled. It would be nice if you were able to get a GT-AX11000 and test it (or someone else who has one).
You need to make sure Windows firewall is disabled across all network types home/public/work, and the allow global rules need to have the source port set to any while the destination port set to the specific port number. And both source and destination address should also be set to any. You can try adding the server executable to dont detect shellcode injections exclusions, but make sure you either restart the application or add to exclusions while the service is not running.
