Multiple Network Address Translation 11-5

In order to support this type of mapping, you define two address ranges. First, you define a public range which contains the first and last public address to be used and the way in which these addresses should be used (PAT, static, or dynamic). You then configure an address map which defines the private IP address or addresses to be used and which public range they should be mapped to. You add the address map to the list of address maps which are configured, creating a map list. The mappings in the map list are order-dependent and are compared in order from the top of the list to the bottom. If a particular resource is not available, subordinate mappings can be defined that will redirect traffic.

Supported traffic

MultiNat supports the following IP protocols:

■PAT: TCP/UDP traffic which does not carry source or destination IP addresses or ports in the data stream (i.e., HTTP, Telnet, ‘r’ commands, tftp, NFS, NTP, SMTP, NNTP, etc.).

■Static NAT: All IP protocol traffic which does not carry or otherwise rely on the source or destination IP addresses in the data stream.

■Dynamic NAT: All IP protocol traffic which does not carry or otherwise rely on the source or destination IP addresses in the data stream.
