A VPN provides a secure communication channel ("tunnel") between two gateway
routers or a remote PC client and a gateway router. The following types of tunnels
can be created:
• Gateway-to-gateway VPN—Connects two or more routers to secure traffic
between remote sites.
• Remote Client (client-to-gateway VPN tunnel)—A remote client, such as a
PC running VPN client software, initiates a VPN tunnel. The IP address of the
remote PC client is not known in advance. The gateway acts as 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. The IP address of the remote NAT router is not known in
advance. The gateway WAN port acts as a responder.
