How to Set Up a Gateway-to-Gateway VPN Configuration

Figure 5-22: Gateway-to-Gateway VPN Tunnel
Follow the procedure below to set the LAN IPs on each FVS318v3 to different subnets and
configure each properly for the Internet.
The LAN IP address ranges of each VPN endpoint must be different. The connection will fail if
both are using the NETGEAR default address range of 192.168.0.x.
In this example, LAN A uses 192.168. 0.1 and LAN B uses 192.1 68. 3.1 .
Note: This section uses the VPN Wizard to set up the VPN tunnel using the VPNC
default parameters listed in Table 5-1 on page 5-4. If you have special requirements not
covered by these VPNC-recommended parameters, refer to Chapter 6, “Advance d
Virtual Private Networking” to set up the VPN tunnel.
