Reference Manual for the Model FVM318 Cable/DSL ProSafe Wireless VPN Security Firewall In some cases, the client PC may connect to the Internet through a local non-VPN-enabled router, as shown below: CLIENT A TA LN T A B AY SC ATLR NA SIM PLE ROUTER INTERNET VPN ROUTER LAN Figure 8-8: Client to LAN access through simple router to VPN router If the non-VPN router is performing NAT, it must support "VPN-passthrough" of IPSec-encoded data. Linking Two Networks Together A VPN between two NETGEAR VPN-enabled routers is a good way to connect branch offices and business partners over the Internet, offering an affordable, high-performance alternative to leased site-to-site lines. The VPN also provides access to remote network resources when NAT is enabled and remote computers have been assigned private IP addresses.
