Allow setting other login url than the default.

Allow setting other login url than the default:

  https://<host>:<port>/dana-na/auth/url_default/login.cgi

so we can login on a vpn login page which needs an url like:

  https://<host>:<port>/dana-na/auth/url_9/login.cgi (example)

Add script to restore DNS server settings to the original DNS settings.

This script will restore the DNS server settings to the original DNS settings
discarding the DNS servers proposed by the VPN client.
This can be useful in cases where the DNS servers proposed by the VPN client
are not accessible over the VPN connection.
