You can ensure that cache server replies always pass back through the ServerIron ADX by
configuring source NAT.
FIGURE 11 Using source NAT with TCS
In this example, the ServerIron ADX and cache server are connected by a router and are in different
sub-nets. In a topology where the cache server’s response is guaranteed to pass back through the
ServerIron ADX, you may not need to configure source NAT. However, if the cache server’s reply can
reach the client by a path that does not pass through the ServerIron ADX, you need to configure
source NAT.
