VPN
A VPN provides a secure communication channel (“tunnel”) between two gateway routers or a remote PC client.
The following types of tunnels can be created:
• Gateway-to-gateway VPN: To connect two or more routers to secure trac between remote
sites.
• Remote Client (client-to-gateway VPN tunnel): A remote client initiates a VPN tunnel as the
IP address of the remote PC client is not known in advance. The gateway in this case acts as a
responder.
• Remote client behind a NAT router: The client has a dynamic IP address and is behind a NAT
Router. The remote PC client at the NAT router initiates a VPN tunnel as the IP address of the
remote NAT router is not known in advance. The gateway Option port acts as responder.
• PPTP server for LAN / Option PPTP client connections.
• L2TP server for LAN / Option L2TP client connections.
