I have set up a no-ip account to access my ssh server at home remotely with
myserver.ddns.net, which works well.. from outside only.
$ ping myserver.ddns.net # success
$ ssh myserver.ddns.net # success
$ ping 192.168.2.8 # success
$ ssh 192.168.2.8 # success
$ ping myserver.ddns.net # success, resolving to 220.127.116.11
$ ssh myserver.ddns.net # loOong time waiting, then.. Connection closed by 18.104.22.168 port 22
Why could it be so?
