Dynamic IP DMZ: 

When a WAN port IP is assigned by ISP and obtained by PPPoE or Dynamic IP, you can use this section to 

specify the DMZ host disregarding the exact WAN IP address. Tick the WAN port option and fill in the IP 

address of the DMZ host inside the network, the IGR-2500 will map the corresponding WAN IP to the internal 

DMZ host automatically. When a remote computer wants to access the internal LAN through this WAN, if the 

accessed port number is not specified by Virtual Server Host, it will be mapped into this internal DMZ host. 

For example, if your WAN1 uses PPPoE connection to obtain a public IP address, the IGR-2500 will let data 

packet with destination address point to WAN1, and pass through into DMZ Host when the port number of the 

packet does not exist in Virtual Server Host table.

Multi-DMZ: 

If you use fixed WAN IP address assigned by your ISP, you can use this section to specifically assign the 

WAN IP address to corresponding DMZ host. If you own several legal WAN IPs, you can assign which WAN 

IP correspond to which IP on your LAN. This assignment will let most protocol to access the assigned IP on 

the LAN. The following figure is an example: (Figure 3-49)
