Plex Media Server forwarding 100+ ports

[Jaether]

Hi there, I've tried looking into this issue but I wasn't able to find anyone having this issue (or if it's even intended). For some reason, there's over 100 ports forwarded by Plex Media server. It doesn't seem like it is intended. Is there a way to remove it quickly without hard resetting my router?

Best bet overall would be to disable the UPNP, this should stop them from auto adding.

The only thing the plex should need external is 32400.
