Seeding discovery with NAT gateway addresses
Seed a NAT discovery by inserting into the Ping finder the IP addresses of the main routers within the system. Also seed the discovery with the IP addresses of the NAT gateway IPs.
About this task
In a NAT-based discovery, the discovery must discover the NAT gateways before discovering the rest of the network, so the NAT gateways must first be found with a finder.
Network Manager is configured to trigger the seeding of all the NAT gateways if NAT translation has been enabled. However, the triggering relies on the Ping finder being active. If seeding is done, for example, using only the File finder, then the NAT gateways are not pinged even if NAT translation has been enabled. It is good practice, therefore, to seed the discovery with all the NAT gateways. You can do this using the File finder, Ping finder, or any other method.
You can also seed the discovery with NAT gateways using the Discovery Configuration GUI.
