Suddenly and for no reason I cannot join anyone in a psn party chat when using the netduma. I have tried using another router with the exact same config as the netduma and it works fine either by using upnp or by port forwarding, but no matter what I do with the duma I cannot use party chat due to nat issues. However it works fine over wifi (but gaming over wifi is not an option).
I have an open nat type in the game but this is a party chat issue and it is really starting to piss me off.
Yes, I have done the standard reboot and reset of the netduma.
