Overview of VPN Configuration
The modem router supports both client-to-gateway and gateway-to-gateway \
VPN tunnels. 
The modem router supports up to five concurrent tunnels.
Client-to-Gateway VPN Tunnels
Client-to-gateway VPN tunnels provide secure access from a remote comput\
er, such as a 
telecommuter connecting to an office network.
