I've run into an issue with how Plutonium handles UPnP port mappings.

Whenever I launch a game through Plutonium, it automatically creates a UPnP port mapping on my router. However, these mappings are created with a lease duration of 0 (infinite), meaning they remain active even after closing the game or restarting my PC.

Since several Call of Duty titles use overlapping port ranges, these persistent mappings seem to interfere with other games, such as Black Ops 3 and newer CoD titles, preventing them from achieving an Open NAT type.

I've confirmed that manually removing the old Plutonium port mappings from my router resolves the issue and allows the affected games to achieve Open NAT again.

Would it be possible for Plutonium to request UPnP port mappings with a limited lease duration and automatically renew them while the game is running?

Alternatively, could Plutonium explicitly remove its UPnP mappings when the game closes?

Is there already a setting or workaround for this?

Thanks in advance!
