ip nat translation (timeouts)

Use this command to configure the IPv4 NAT maximum timeout value in seconds per flow type.

Syntax

ip nat translation {timeout | udp-timeout | tcp-timeout | icmp-timeout | dns-timeout | ftp-timeout | finrst-timeout} [seconds]

no ip nat translation {timeout | udp-timeout | tcp-timeout | icmp-timeout | dns-timeout | ftp-timeout | finrst-timeout}

timeout	Specifies the timeout value applied to dynamic translations. Default: 240 seconds.
udp-timeout	Specifies the timeout value applied to the UDP translations. Default: 240 seconds.
tcp-timeout	Specifies the timeout value applied to the TCP translations. Default: 240 seconds.
icmp-timeout	Specifies the timeout value applied to the ICMP translations. Default: 240 seconds.
dns-timeout	Specifies the timeout value applied to the DNS translations. Default: 240 seconds.
ftp-timeout	Specifies the timeout value applied to the FTP translations. Default: 240 seconds.
finrst-timeout	Specifies the delay applied after the TCP finish reset (FIN/RST) is observed on an IPv4 NAT binding.
`seconds`	(Optional) Specifies the timeout value in seconds.

If seconds is not specified, the default value of 240 seconds is applied.

Configuration command, Global configuration.

The “no” form of the command resets the timeouts to the default value of 240 seconds.

This example sets the NAT IPv4 timeout value applied to UDP flows to 400 seconds:

System(rw-config)->ip nat translation udp-timeout 400
