3.11.4 Multi-NAT
Multi-NAT function allows you to configure multiple LAN IP domain to each WAN port (total 10 LAN IP can be
defined), after configure multiple NAT function it will act like virtual router, all traffic between each LAN IP
domain will be accessed through IGR-2500. It will provide following benefit:
Restrict broadcast storm in single IP domain.
Check each packet with DoS function enable.
