ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308

IPv4 Static Route Example

In this example, we assume the following:
•The VPN firewall’s primary Internet access is through a cable modem to an ISP.
•The VPN firewall is on a local LAN with IP address 192.168.1.100.
•The VPN firewall connects to a remote network where you need to access a device.
•The LAN IP address of the remote network is 134.177.0.0.
When you first configured the VPN firewall, two implicit static routes were created:
•A default static route was created with your ISP as the gateway.
•A second static route was created to the local LAN for all 192.168.1.x addresses.
With this configuration, if you attempt to access a device on the 134.177.0.0 remote network,
the VPN firewall forwards your request to the ISP. In turn, the ISP forwards your request to
the remote network, where the request is likely to be denied by the remote network’s firewall.
In this case, you need to define a static route, informing the VPN firewall that the 134.177.0.0
IP address should be accessed through the local LAN IP address (192.168.1.100).
The static route on the VPN firewall needs to be defined as follows:
•The destination IP address and IP subnet mask need to specify that the static route
applies to all 134.177.x.x IP addresses.
•The gateway IP address needs to specify that all traffic for the 134.177.x.x IP addresses
should be forwarded to the local LAN IP address (192.168.1.100).
•A metric value of 1 should work since the VPN firewall is on the local LAN.
•The static route can be made private only as a precautionary security measure in case
RIP is activated.
Manage Static IPv6 Routing
At this time, NETGEAR’s implementation of IPv6 does not support RIP next generation
(RIPng) to exchange routing information, and dynamic changes to IPv6 routes are not
possible. To enable routers to exchange information over a static IPv6 route, you need to
manually configure the static route information on each router.
To add an IPv6 static route to the Static Route table:
1. Select Network Configuration > Routing.
2. In the upper right of the screen, select the IPv6 radio button. The Static Routing screen
displays the IPv6 settings:
