System information

Installing and Conﬁguring the VPN Client 175

• Uninstall VPN Client—Uninstall the application. You can choose to retain connection

and certiﬁcate information.

• VPN Dialer—Manage connection information and start a connection with a VPN host

device. This poorly named function is the main functional area of the VPN Client.

You can use the VPN Client with dial-up, ISDN, cable, or DSL modems as well as with direct

LAN connections. How you get to the Internet does not matter to the VPN Client. The only

requirement is that the client device can “see” the host device using TCP/IP.
