nat Command
The nat (Network Address Translation) command lets you dynamically translate a set of IP
addresses (usually on the inside) to a global set of IP addresses.
The nat command is always paired with a global command, with the exception of the nat 0
command. Table 6-5 describes the command parameters for the nat command, the syntax of
which is as follows:
nat (if-name) nat-id local-ip [netmask] [dns] [[tcp] tcp_max_conns [emb_limit]
[norandomseq]]] [udp udp_max_conns]
1 NAT = Network Address Translation
2 DNS = Domain Name System
3 UDP = User Datagram Protocol
NOTE PIX version 6.2 and later support bidirectional translation of inside network IP
addresses to global IP addresses and translation of outside IP addresses to inside network
IP addresses.
