The following table describes the
WAN Configuration
settings:
Field Name
Description
Bridge
Select ENABLE to connect the LAN to the WAN (i.e. bridge the
two connections). This is available in Bridge Mode only. The
default setting is DISABLED.
IGMP
This refers to the IGMP (Internet Group Management Protocol)
relay/proxy specification and environment. The default is
DISABLEDI. IGMP is available in all modes and all encapsulations.
The Support for IGMP proxy/relay function for ADSL Bridge/Router
is based on the following requirement and cases:
On the CO side, there must be at least one IGMP querier (router)
present. IGMP querier will send the IGMP query packet. The ADSL
Bridge/Router is responsible to relay these IGMP queries to
Ethernet.
End-user multicast application device sends IGMP report while
receiving IGMP query or being activated by the user. The ADSL
Bridge/Router should be responsible to proxy (that is, change
source IP to ADSL Bridge/Router’s WAN IP) the IGMP report to
ADSL WAN side, including all PVCs (Permanent Virtual Circuits).
The same case is for IGMP leave packet.
It is not necessary to relay multicast routing between two ADSL
PVCs or two interfaces in LAN side.
Special purpose multicast packets (such as RIP 2 packets) should
run without interference.
Static IP Settings
These settings are for users who have a Static IP Address with
their VSP on the WAN side.
IP Address
refers to the Static IP Address given by your VSP. The
range for the IP Addresses is x.x.x.y, where 0< x < 255 and 1 < y
< 254 and the default is 0.0.0.0.
Subnet Mask
refers to the subnet mask given by your VSP. The
range for Subnet Mask is x.x.x.x , where 0< x < 255 and the default
is 255.0.0.0.
Gateway
refers to the gateway given by your VSP. The range for
Gateway is x.x.x.y, where 0< x < 255 and 1 < y < 254 and the
default is 0.0.0.0.
DHCP Client
This function enables or disables the ADSL Bridge/Router WAN as
a DHCP client, where the VSP would be the DHCP Server. The
default is set to DISABLED. DHCP clients are generally used in the
following encapsulations:
1483 Bridged IP LLC
1493 Routed IP LLC
1483 Bridged IP VC-MUX
