tables are displayed in the PPTP VPN Client menu. VPN Connection Status provides
information about the State of the VPN (i.e. enabled or disabled) and the Status of the
connection (i.e. up or down).
The VPN Configuration table provides the ability to enable/disable the VPN, edit the
VPN configuration, delete the VPN entry and edit the advanced routing information.
L2TP client
The Layer Two Tunneling Protocol was developed by Microsoft and Cisco as a
multi-purpose network transport protocol.
Many DSL ISPs use L2TP over ATM to create tunnels across the Internet backbone.
The Shiva VPN Gateway L2TP implementation can only run L2TP over Ethernet since
it doesn't have an ATM adapter. L2TP packets are encapsulated in UDP packets on
port 1701 and sent over Ethernet to the L2TP server.
The Shiva VPN Gateway L2TP VPN client is configured and operates in a similar way
to the PPTP VPN Client.
