This solution applies to the Barracuda Web Security Flex service.
Answer:Yes. The configuration needed for Transparent Forward Proxy is forwarding all port 80 traffic from the LAN to the External port 8080 of External IP address of your service host.
The service host can be found at the bottom of the Support Tab of the Web Security Flex Administrative Portal. You can resolve this by completing an nslookup within command/DOS on a Microsoft Windows System.
Service Host = ple7.flex.purewire.com
In this example, we will need to complete a NAT Port Forward on the firewall to forward all port 80 traffic from the LAN to the External IP of Service Host which is 18.104.22.168 and the External Port of 8080.
