General Network Advice

[penzo.livio]

My experience: in one night, my tests tested favorably, failed testing, and experienced the “could not connect to test server” status. Shortly later that evening, tests were fine again. No configuration was needed on my out of the box, home/consumer grade  modem  nor router.

Now rereading: “Public IP” refers to your home/office network’s modem’s  outbound IP address. If you’ve paid for a status or have dynamic thru your  ISP, public is what you see when you present yourself to the WAN (the web). Check out  https://whatismyip.com/ for instance.

My guess is that in most cases nobody had to do anything with his network setup...

Unfortunately my experience is opposite, I am unable to connect to any partner, since the beginning I always get a No audio from partners. Talking with ISP the router has UPnP enabled, public access and udp ports set to 12000 and 12001, as requested somewhere in this forum. What should I do ? Please help.
