In Flow 1b, the ServerIron ADX changes the destination address in Flow 1a to that of the cache
server. CAM programming is the same as for basic TCS, as detailed in Table 1.
NOTE
FTP is not supported for TCS with destination NAT.
TCS with source NAT
To make sure that the reverse traffic from the cache server hits the ServerIron ADX, source NAT may be
used as shown in the following diagram:
