Whenever I go to my router's configuration > NAT > Virtual Servers, I see many entries titled "Skype UDP at 10.0.0.X:< port> (< port>)". I believe that these are being made by the Skype client on different hosts, to allow some sort of functionality. How does Skype manage to get access to port-forwarding? Is there any way to disable this?
I have the Zyxel VMG1312-B30B router

– DavidPostill – 2016-07-17T12:05:23.137@DavidPostill My UPnP was activated. I will disable it and report if the Skype entries re-appear – TheBro21 – 2016-07-17T12:05:45.577
