LAN WAN or DMZ WAN Inbound Rule: Setting Up One-to-One NAT Mapping
In this example, we will configure multi-NAT to support multiple public IP addresses on one WAN
interface. By creating an inbound rule, we will configure the UTM to host an additional public IP
address and associate this address with a Web server on the LAN.
The following addressing scheme is used to illustrate this procedure:
• Netgear UTM:
– WAN1 IP address (dual-WAN port models) or WAN IP address (single-WAN port
models): 10.1.0.118
– LAN IP address subnet: 192.168.1.1; subnet 255.255.255.0
– DMZ IP address subnet: 192.168.10.1; subnet 255.255.255.0
• Web server PC on the UTM’s LAN
– LAN IP address: 192.168.1.2
– DMZ IP Address: 192.168.10.2
– Access to Web server is (simulated) public IP address: 10.1.0.52
