UAG and F5 SSL communication

Current designing and wondering if there is anything we may need to consider regarding passing SSL traffic to Microsoft's UAG.

If we use the F5 to do unencrypting and re-encrytping of the packet, will UAG react different to that packet?

I'm investigating doing a SSL re-encryption, which is contrary to the design that is currently being looked at. Right now, the design consideration is to do SSL passthrough all the way to UAG, and that would limit our ability to inspect and know what is going on from a security packet inspection.

Looking for guidance
