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.
Figure 3-51 Multi-NAT
„ LAN IP: separated LAN IP domain
„ Subnet Mask: mask for IP domain
„ WAN IP: specific WAN IP address matched to LAN IP domain.
‹ You can leave it blank in this field for PPPoE connection.
‹ Write down specific WAN IP address, if WAN port had defined multiple IP address on it (DMZ
used).
‹ Blank: router will send packet follow by WAN filed selected.
„ WAN: AUTO, WAN1, WAN2, WAN3, WAN4, WAN5
‹ WAN1/2/3/4: router will route packet to correspond LAN/WAN
‹ AUTO: router will route packet follow by “load balance” function selected
