Direct attached routes are routing entries for network that can be reached from an interface of the Barracuda NextGen Firewall F-Series without having to use a next hop gateway.
Before you begin
Connect the network to a port of the Barracuda NextGen Firewall F-Series. Do not use the management port.
Step 1. Configure a direct route
Add a route for the direct attached network.
- Go to CONFIGURATION > Configuration Tree > Box > Network.
- In the left menu, click Routing.
- Click Lock.
- In the IPv4 Routing Table table, click + to add a route:
- Name – Enter a name.
- Target Network Address – Enter the network in CIDR format. E.g.,
- Route Type – Select direct attached network.
- Interface Name – Select the interface used to connect to the network. E..g, eth1
- Trust Level – Select the trust level. Your network will automatically be connected to the corresponding network objects. Use Untrusted for WAN connections, Trusted for LAN connections.
- (optional) Advertise Route – To propagate this network route via the OSPF/RIP/BGP service, select Yes. For more information, see Dynamic Routing Protocols (OSPF/RIP/BGP)
- Click OK.
- Click Send Changes and Activate.
Step 2. Activate the network configuration
After you have configured the network route, you must activate your new network configuration.
- Go to CONTROL > Box.
- In the left menu, expand Network and click Activate new network configuration.
- Select Failsafe The Network Activation Succeeded message is displayed after your new network configurations have been successfully activated.
The direct attached route is now displayed as pending on the CONTROL > Network page. To make the route active, you must use one of the IP addresses in the network as a virtual server IP address (default) or as an additional IP address (remote units).
You must use at least one IP address from the network as a virtual server IP address. If you are using a high availability setup, these virtual server IP addresses will be transferred to the secondary NextGen Firewall F-Series in case of a failure.
