You have to provide IP address, port number and, if needed, a username. If a password is required, you will be
prompted for it when connecting. Common port numbers are 3128 or 8080. Your network administrator will be
able to provide the correct values.
This section contains some options for fine tuning the VPN client. Not all entries are mandatory. Some
entries depend on the used Proxy type.

Following modes are available:

such as ISDN cards to hang-up the line during idle time. Otherwise the
communication between client and server would always trigger a connection.
