ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
IPv4 Static Route Example
In this example, we assume the following:
• T
he VPN firewall’s primary Internet access is through a cable modem to an ISP.
• T
he VPN firewall is on a local LAN with IP address 192.168.1.100.
• T
he VPN firewall connects to a remote network where you need to access a device.
• T
he LAN IP address of the remote network is 134.177.0.0.
When you first configured the VPN firewall, two implicit st
atic routes were created:
• A d
efault static route was created with your ISP as the gateway.
• A seco
nd 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,
t
he 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:
• T
he destination IP address and IP subnet mask need to specify that the static route
applies to all 134.177.x.x IP addresses.
• T
he 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.
• T
he 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 Configuratio
n > Routing.
2. In the upper
right of the screen, select the IPv6 radio button. The Static Routing screen
displays the IPv6 settings:
