How to Set Up a Gateway-to-Gateway VPN Configuration
Follow this procedure to configure a gateway-to-gateway VPN tunnel using the VPN Wizard.
Note: While your PC is connected to a remote LAN through a VPN, you might not have
normal Internet access. If this is the case, you will need to close the VPN
connection in order to have normal Internet access.
Note: This section uses the VPN Wizard to set up the VPN tunnel using the VPNC
default parameters listed in Table 6-2 on page -4. If you have special requirements
not covered by these VPNC-recommended parameters, refer to “How to Set Up
VPN Tunnels in Special Circumstances” on page -36 to set up the VPN tunnel.
