Address Translation and LB VSs

It makes sense when you want the BigIP to be 'transparent' to the traffic. Two scenarios are

1. When building a firewall-sandwich
2. Acting as a router (effectively the same as 1)
3. When running a VS and the pool members can't handle NAT'ing (Specific to the protocol usually). The VS IP is usually configured on the loopback address of the pool member, and is sometimes termed n-path
