A site wishes to perform source address translation on packets from some clients but not others. The determination is not based on the client's IP address, but on the virtual servers their packets arrive on. What could best accomplish this goal?
A. A SNAT for all addresses could be defined, and then disable the SNAT processing for select VLANs
B. Some virtual servers could be associated with SNAT pools and others not associated with SNAT pools
C. The decision to perform source address translation is always based on VLAN
D. The decision to perform source address translation is always based on a client's address (or network)
