This article refers to firmware 4.2 and higher running on the Barracuda Load Balancer model 640 that includes PORT1 through PORT10, except where noted.
You can configure the WAN IP Address on a VLAN, on the WAN Port, or as a bonded interface. By default the WAN IP is configured on the WAN Port as an untagged network.
Configure the WAN IP Address on a VLAN Network
If this is your initial deployment, you can configure the Barracuda Load Balancer in a WAN VLAN network by configuring the VLAN Network ID to the System VLAN ID while configuring the System IP through consconf. However, if you previously configured your Barracuda Load Balancer in a different deployment and wish to move the WAN IP to VLAN network from an untagged network, you must create a VLAN Interface in the VLAN Configuration section on the ADVANCED > Advanced Networking page:
- Log into the web interface, and in the VLAN Configuration section on the ADVANCED > Advanced Networking page, enter the VLAN Name, VLAN ID, and select WAN from the Port menu.
- Click Add.
- In the WAN IP Configuration section on the BASIC > IP Configuration page, select the port value of the VLAN Name you defined in Step 1 above, and click Save Changes.
Configure the WAN IP as a Bonded Interface
This section refers to firmware 4.2 and higher running on the Barracuda Load Balancer model 640 that includes PORT1 through PORT10.
You can configure the Barracuda Load Balancer WAN IP as a bonded interface using the following steps:
- Log into the web interface, and go to the ADVANCED > Advanced Networking page.
- In the Link Bonding section, click Add Interface Bond.
- Enter a name for the link bond, and select the mode.
- Highlight the WAN port, and click Add to move the WAN port to the Ports list.
Click Add at the top of the page to create the bond interface and automatically add the WAN IP, custom virtual interfaces, static routes, and source network address translation created on the WAN port and VLANs.
Configure the WAN IP on a VLAN Network of a Bonded Interface
You can configure the Barracuda Load Balancer WAN IP on a VLAN Network of a bonded interface using the following steps:
- Log into the web interface, and go to the ADVANCED > Advanced Networking page.
- In the VLAN Configuration section, enter the name and ID in the VLAN Name and VLAN ID fields, and from the Port menu, select WAN.
- Click Add.
- In the WAN IP Configuration section on the BASIC > IP Configuration page, select the Port value to the VLAN Configuration you created in Step 2 above.
- Go to the ADVANCED > Advanced Networking page, and in the Link Bonding section, click Add Interface Bond.
- Enter a name for the link bond and select the mode.
- Highlight the WAN port and click Add to move the WAN port to the Ports list.
Click Add at the top of the page to create the bond interface and automatically add the WAN IP, custom virtual interfaces, static routes, and source network address translation created on the WAN port and VLANs.
