DMZ: A DMZ (De-Militarized Zone) is added between a protected network and an external network, in 
order to provide an additional layer of security. When there is a suspected packet coming from WAN, the 
firewall will forward this packet to the DMZ host.
DMZ Host IP: The IP address of the DMZ host at LAN side.
IGMP Proxy: Here is the global setting for IGMP Proxy. If it is enabled, then the enabled IGMP Proxy on 
WAN PVCs will be working. Otherwise, no WAN PVC can have IGMP Proxy working on it.
PPP Half Bridge: When the PPP Half Bridge is enabled, only one PC is able to access the Internet, and 
the DHCP server will duplicate the WAN IP address from the ISP to the local client PC. Only the PC with 
the WAN IP address can access the Internet.
Q: What is the difference between PPP connect on WAN access and the Automatic Reconnect?
A: Some ISPs terminated the PPP session due to the inactivity.
PPP reconnect on WAN access: If it is enabled, the PPP will be automatically reconnected when an 
URL is entered in the browser (packet interested in going out the WAN).
Connect PPP when ADSL link is up: If it is enabled, the PPP session will be automatically established 
when ADSL link is available. 
SNTP: This field allows user to set time zone and enable/disable daylight saving time option.
