F5 Bridge design

Just to clarify, F5 devices can bridge different VLANs into a single broadcast domain, and the options (transparent, translucent and opaque) relate to how VLAN bridging is achieved.

You must understand what you are trying to achieve and the behaviour of these modes if you wish to implement VLAN bridging - it is probably the easiest way to disrupt traffic in odd and difficult to trace ways. There is almost always a better and more understandable solution than VLAN bridging.

This has vary little to do with Virtual Servers which are (generally) proxy services that rewrite packet IP addresses based on the SNAT/SNAT automap settings. As long as the gateway can see the virtual server on one subnet and the pool members on another, no bridging should be required.
