Why can't I access websites over non-standard ports when using a Barracuda Web Filter as a forward proxy?

Solution #00003339

Scope:
All Barracuda Web Filters deployed in forward proxy mode, all firmware versions.

Answer:
When using the Barracuda Web Filter in forward proxy mode, it will by default only forward HTTP and HTTPS connections over ports 3128, 8080, 443, and 21. If you need to proxy to additional ports, you must add them on the Advanced > Proxy page.

Once there, scroll down until you see the HTTP Ports and HTTPS Ports fields. If you need to proxy HTTP or HTTPS on an additional port, add it into the corresponding field and click the Add button. You do not need to add ports 3128, 8080 as HTTP or port 443 as HTTPS because these default ports will work without any additional configuration.
