All Barracuda Web Application Firewalls.
The Barracuda Web Application Firewall can be deployed in Proxy or Bridge mode. The unit is shipped with Bridge mode enabled. If the operation mode is changed from Bridge-Path to Proxy, you may receive the error (Virtual port configured) if you previously added virtual interfaces to the physical port to communicate with the servers.
Before changing operation modes you should remove any previously configured information that may cause conflict or errors, as follows:
- BASIC > Services – Remove any services you have configured.
- ADVANCED > Advanced IP Config – Remove any virtual interfaces, static routes, and interface routes you have configured.
