Create a static route to specify a gateway for an unassociated network so that the return traffic can take the correct path. In general, you must add a static route when you want to reach networks that are not directly attached to the Barracuda NextGen X-Series Firewall or the default gateway.
Add a Static Route
- Go to NETWORK > Routing.
- In the Target Network field of the Static Route Configuration section, enter the IP address and netmask of the target network in CIDR format, e.g.,
- In the Gateway field, enter the IP address of the next hop or gateway. This gateway must be reachable by a direct route.
- If you must specify the source IP address used with this gateway, enter it in the Source Address field.
- From the Classification drop-down menu, select the relevant network.
Specify Metric and Maximum Transmission Unit (MTU) for the route, if required.
- Click Add.
- At the top of the page, click on the warning message to execute the new network configuration.
The static route is now displayed in the NETWORK ROUTES table.
(optional) Add a Reachable IP to the Static Route
After your have successfully added a static route, you have the option to assign an IP address that can be reached via this route. This is indicated by the Options button.
- Click Options.
- The window for configuring Static Route Configuration Options is displayed.
- Enter the IP address that you want to reach via the static route.
- Click + to add the IP address to the setting.
- Click Save to save or Cancel to discard the changes.
