Re: Doctor, where have you been all this time ?
"P.S. No... I do NOT have any problems playing games, talking on Skype, etc. etc. etc. Never have had. And I forward precisely ZERO ports."
Most likely you are playing games that do not require peer-to-peer access between players. Some games, particularly Xbox games, but also PC (eg. Elite Dangerous) do require it however and won't work without either uPnP or manual port fowarding.
As regards Skype, I suspect it falls back to a centralised server (ie. middleman) approach if it cannot establish a direct connection between users.
