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.
MultiNAT Configuration
You configure the MultiNAT features through the console menu:
■ For a simple 1-to-many NAT configuration (classic NAT), use the Basic configuration – Easy Setup Profile,
described below.
■ For the more advanced features, such as Server Lists and Dynamic NAT, follow the instructions in “IP
setup” on page 9-7.
