7.4.4. All-to-One IP Translation
NetDefendOS can be used to translate a range or a network to a single IP address. Suppose that
the requirement is to translate a range of destination IPv4 addresses which includes 194.1.2.16 to
194.1.2.20 plus 194.1.2.30 to the single IPv4 address 102.168.0.50. The port number will remain
unchanged.
