' There are three primary reasons that the VA would be used:

a)When the IPSec gateway performs assignment of the WINS address via Mode Configuration protocol. Without the VA, the client can accept a private IP address / mask and DNS address, but not WINS.

b)When the client is on a Windows 2000 Operating System and the IPsec gateway assigns DNS address via Mode Config. Due to changes in the operating system, the client supports DNS assignment via Mode Config on other operating systems but not Windows 2000 unless a VA is used.

c)When there is a requirement that the assigned address be visible to user' applications on the client system. When the VA is not used, the source address of each IP packet is automatically changed prior to leaving the client machine (similar to NAT). This can cause problems for certain applications that use the IP address.
