Default Route
The default route section allows the administrator to define the default network route by setting the default
IPv4 gateway and interface, and/or default IPv6 gateway and interface. A default network route is required for
Internet access.
Static Routes
The static routes section allows the administrator to add and configure additional static routes by specifying a
destination network, subnet mask, optional default gateway, and interface.
Configuring a Default Route for the SMA/SRA
Appliance
You must configure a default gateway on your SMA/SRA appliance for it to be able to communicate with remote
networks. A remote network is any IP subnet different from its own. In most cases, the default gateway is the
LAN IP address of the firewall interface to which the SMA/SRA appliance is connected. This is the default route
for the appliance.
To configure the default route:
1 Navigate to the Network > Routes page.
2In the Default IPv4 Gateway field, type the IP address of the firewall or other gateway device through
which the SMA/SRA appliance connects to the network. This address acts as the default route for the
appliance.
3In the Interface drop-down list, select the interface that serves as the IPv4 connecting interface to the
network. In most cases, the interface is X0.
4In the Default IPv6 Gateway field, type the IPv6 address of the firewall or other gateway device
through which the SMA/SRA appliance connects to the network. This address acts as the default IPv6
route for the appliance.
5In the Interface drop-down list, select the interface that serves as the IPv6 connecting interface to the
network.
6Click Accept.
Configuring Static Routes for the Appliance
Based on your network’s topology, you might find it necessary or preferable to configure static routes to certain
subnets rather than attempting to reach them through the default gateway. While the default route is the
default gateway for the device, static routes can be added as needed to make other networks reachable for the
SMA/SRA appliance. For more details on routing or static routes, refer to a standard Linux reference guide.
To configure a static route to an explicit destination for the appliance, complete the following
steps:
1 Navigate to the Network > Routes page and click Add Static Route...
2In the Add Static Route dialog box, type the subnet or host to which the static route is directed into the
Destination Network field (for example, 192.168.220.0 provides a route to the 192.168.220.X/24
subnet). You can enter an IPv6 subnet (for example, 2007:1:2::).
