Configuring One-Arm Proxy

In One-Arm proxy mode, the device uses only the WAN port for both incoming and outgoing traffic. Do the following to configure One-Arm Proxy mode:

  1. Go to the BASIC > IP Configuration page.
  2. Specify values for the following in the WAN IP Configuration section:
    • IP Address
    • Subnet Mask
    • Default Gateway
  3. In the Operation Mode section, set the Mode of Operation to Proxy.
  4. Enter Default Host Name and Default Domain in the Domain Configuration section. The Default Host Name is used in reporting, and the Default Domain is the domain for the system.
  5. Click Save.

    If you want to switch from Proxy to Bridge mode or Bridge to Proxy mode, you have to remove all configured Services, VLANs and Virtual Interfaces on the device. You can remove services on the BASIC > Services page, and VLANs and Virtual Interfaces on the ADVANCED > Advanced IP Config page. Note that Bridge Mode is not supported by the Barracuda Web Application Firewall Vx virtual machine.
