10.4.7 Configuring the Interval at Which NAT Sends Gratuitous ARP Packets
Networking
Requirements
Configure the interval at which gratuitous ARP packets are sent from addresses in the NAT address pool, so as to avoid
address conflicts.
Notes
Sending gratuitous ARP packets is disabled by default on the NAT device.
Gratuitous ARP packets are sent to the outside interface only.
Configuration Steps
Configuring the NAT Inside Interface
Mandatory configuration.
Unless otherwise noted, the interface connecting intranet should be configured as the NAT inside interface.
Configuring the NAT Outside Interface
Mandatory configuration.
Unless otherwise noted, the interface connecting extranet should be configured as the NAT outside interface.
Configuring Static NAT
Optional configuration.
Configure static NAT in global configuration mode when a small number of users in the intranet need to access the
extranet.
Configuring Dynamic NAT
Optional configuration.
Configure dynamic NAT in global configuration mode when a large number of users in the intranet need to access
the extranet.
Configuring the Interval at Which NAT Sends Gratuitous ARP Packets
Optional configuration.
NAT needs to consider some addresses matching the configured rule as local addresses. This configuration is
performed to avoid address conflicts.
