Dial on Demand
The device can be configured to disconnect if there is no activity for a period of time
by selecting this check box. When the checkbox is ticked, you must enter the
inactivity timeout period. The timeout period ranges from 1 to 4320 minutes.
PPP IP Extension
The PPP IP Extension is a special feature deployed by some service providers.
Unless your service provider specifically requires this setup, do not select it.
PPP IP Extension does the following:
Allows only one PC on the LAN
The public IP address assigned by the remote side using the PPP/IPCP
protocol is actually not used on the WAN PPP interface. Instead, it is
forwarded to the PC LAN interface through DHCP. Only one PC on the
LAN can be connected to the remote, since the DHCP server within the
device has only a single IP address to assign to a LAN device.
NAT and firewall are disabled when this option is selected.
The device becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The device extends the IP subnet at the remote service provider to the
LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.
The device bridges the IP packets between WAN and LAN ports, unless
the packet is addressed to the device's LAN IP address.
Use Static IP Address
Unless your service provider specially requires this setup, do not select the
checkbox. If selected, enter the static IP address in the IP Address box.
Enable PPP Debug Mode
More PPP connection information will be listed in the System Log. This is used for
debugging. Please don't enable it for normal usage as it uses system resources.
STEP 4: This screen allows the user to control IGMP Multicast and WAN Service.
Enable IGMP Multicast checkbox:
Tick the checkbox to enable IGMP multicast (proxy). IGMP (Internet Group
Membership Protocol) is a protocol used by IP hosts to report their multicast group
memberships to any immediately neighboring multicast routers.
