Scope:
This solution applies to the Barracuda Web Application Firewall, all firmware versions.

Answer:
The main differences between the Proxy Mode and the Bridge Mode are as follows:

Proxy Mode
  1. Supports the creation of HTTP/HTTPS, Instant SSL, redirect, custom SSL/FTP/SSL services.
  2. You can configure Network ACL, Source NAT and Destination NAT.
  3. Instant SSL, Real server Load Balancing, TCP Pooling, Content Routing, Caching, and Compression can be achieved (some of these features are not included in 360 model).
  4. During configuration, more network changes are required.
  5. Features like Hardware bypass and bypass on failure are not available.
  6. Requests coming to a non-VIP configured on Web Application Firewall are dropped.
  7. In proxy mode, services not configured as VIP are not allowed to pass through the box.

Bridge Mode
  1. You can create HTTP and HTTPS services only.
  2. You cannot configure Network ACL, Source NAT or Destination NAT in this mode.
  3. Instant SSL, etc., are not available in this mode.
  4. Fewer network changes are required, since the existing IP Address infrastructure is reused.
  5. Features like Hardware bypass and bypass on failure are only available in this mode.
  6. In bridge mode, services not configured as VIP are allowed to pass through the box by default.
