Some operators require that you log on a web page to get network connectivity. The firewall can perform this logon automatically.
Right now, Ingate Firewall can only manage auto logon to Telia servers.

Select your Internet operator.
Enter the username and password provided by your Internet operator.
The firewall needs a server to ping in order to check the connection status. This keep alive server must be located on the remote side of your operator's connection to you.
