Hi folks & Volk & Gilgongo
I just though something ATM while reading posts of people complaining with that kind of issues. I just post it as is as I can't investigate because too busy with fighting againt jack/qjackctl.
Well here it is : for some months one ISP ("Free" and maybe others) in France (and maybe elsewhere) began to share the single public IPv4 they previously provided to a single subscriber between 4 subscribers : roughly they do this by splitting the 0-65535 port range into 4 sub-ranges they assign to the 4 subscribers.
And they now force-enable IPv6 in their routers (was previouly optionnal).
Maybe this is related to the end of new IPv4 availability.
Whatever THIS ISP allows aware users to reclaim a full own IPv4 port range (free of charge), simply a checkbox from within their subscribers control panel (requieres router reboot).
Hope this is not noise
Thanks for heavy job
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Interesting - although I'm not sure I understand "splitting the 0-65535 port range into 4 sub-ranges they assign to the 4 subscribers". IPv6 for home broadband is I suppose only going to get more common though.

I don't know exactly how they do this. The main idea here behind is that only a few run a server behind the NAT box, so none of them need to have e.g. port 80 or 22 (or 22124 ;-) ) available....
Let's dig a bit...
