„ Public DMZ: Public IP Mapping
This AirLive IGR-2500 provides “Public IP Mapping” function. With this function you can map legal IP between
ROUTER WAN & LAN interface. This application will be very useful to let you connect GAME Server or VOIP
gateway inside the LAN, because most GAME SERVER or VOIP gateway needs legal IP address to
operation.
For Example:
ISP provides following legal IP address to your office. (Static IP 203.74.94.31 ~ 34)
By using DMZ function, you can configure DMZ host as follow.
DMZ Host IP Address IP address provided by ISP
192.168.1.10 203.74.94.32 (private DMZ host)
203.74.94.33 203.74.94.33 (for GAME SERVER)
203.74.94.34 203.74.94.34 (for VOIP gateway)
After configure IGR-2500 as above DMZ HOST table, the IGR-2500 will redirect the packets which destination
address points to 203.74.94.33/34 into GAME SRVER and VOIP gateway .It also allows LAN user (ex.
192.168.1.xx) to access GAME SERVER or VOIP gateway. (Figure 3-50)
