ip nat translation
The ip nat translation command is replaced by the ip nat translation (timeout) and ip nat translation max-entries commands. See these commands for more information.
ip nat translation (timeout)
To change the amount of time after which Network Address Translation (NAT) translations time out, use the ip nat translation command in global configuration mode. To disable the timeout, use the no form of this command.
ip nat translation {timeout | udp-timeout | dns-timeout | tcp-timeout | finrst-timeout | icmp-timeout | pptp-timeout | syn-timeout | port-timeout} {seconds | never}
no ip nat translation {timeout | udp-timeout | dns-timeout | tcp-timeout | finrst-timeout | icmp-timeout | pptp-timeout | syn-timeout | port-timeout}
