Network Address Translation Configuration Managing Dynamic Bindings
You force address translation of all flows to and from the inside local pool by entering the following command in
Configure mode.
21.3 MANAGING DYNAMIC BINDINGS
As mentioned previously, dynamic address bindings expire only after a period of non-use or when they are manually
deleted. The default timeout for dynamic address bindings is 1440 minutes (24 hours). You can manually delete
dynamic address bindings for a specific address pool or delete all dynamic address bindings.
To set the timeout for dynamic address bindings, enter the following command in Configure mode.
To flush dynamic address bindings, enter the following command in Enable mode.
21.4 NAT AND DNS
NAT can translate an address that appears in a Domain Name System (DNS) response to a name or inverse lookup.
For example, if an outside host sends a name lookup to an inside DNS server, the inside DNS server can respond with
a local IP address, which NAT translates to a global address.
To enable NAT DNS translation, enter the following command in Configure mode:
Force all flows to and from local address pool to be
translated.
