Install IPV6 on our network - convert IPV6 to IPV4 tunnel.
You are using an IPV6 server and port forwarding to IPV4. This means the IP will always stay the same, but the port is different. See the following example:
our SERVER is not binding the Proxies by IP, but by username and password. So the TEXT file you provide us has to include the UN:PW after the Port.
