Advanced
DHCP Target IP: The DHCP server runs on WAN 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 connect on WAN access: If it is enabled, the PPP session will be automatically
established when there is a packet wants to go out the WAN.
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. This function
should only be used if one computer will be allowed to connect to the internet (E.G a
Software firewall computer or Proxy server)
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. For the PPP connect on WAN
access, the PPP will be automatically reconnected when an URL is entered in the browser
(packet interested in going out the WAN). For the Automatic Reconnect, it will reconnect the
PPP session whenever it is terminated by ISP.
