IGMP Proxy
The Internet Group Management Protocol (IGMP) is an Internet protocol that provides a way for an Internet
computer to report its multicast group membership to adjacent routers.
The hosts interact with the system through the exchange of IGMP messages. When you want to configure IGMP
proxy, the system will interact with other router through the exchange of IGMP messages. However, when acting as
the proxy, the system performs the host portion of the IGMP task as follows:
±
When it is queried, the system will send group membership reports to the group.
±
±
When one of the hosts joins a multicast address group to which none of other hosts belong, the system
will send unsolicited group membership reports to that group.
±
±
When the last of hosts in a particular multicast group leaves the group, the system will send a leave group
membership report to the routers group.
±
To enable the IGMP Proxy function, please open
Configuration >IGMP
.
Enabled on PVC:
Check this button and choose the interface and click
Apply
to invoke the IGMP settings.
Disable:

Chapter 6: Troubleshooting
If the suggested solutions in this section do not resolve your issue, contact your system administrator or Internet
service provider.
Problems with LAN
PCs on the LAN can not get IP addresses from the ADSL Router.
The chances are that the interface used as DHCP server is modified and the client PCs do not renew IP addresses.
If your DHCP server is enabled on Private IP Address previously and you modify the interface to Public IP Address,
the client PCs should renew IP addresses.
The PC on the LAN cannot access the Web page of the ADSL Router.
Check that your PC is on the same subnet with the ADSL Router.
The virtual server can’t be access after setting virtual server.
Check the filter rule of the port that virtual server service setting for example, the virtual server service set FTP 21
you need update the filter rule of the ftp 21
Direction
setting
:
Choose
filter the packets that incoming action (In
Bound) are
Allow
on the interface.
Problems with WAN
You cannot access the Internet.
±
If your ADSL Router is set to routing mode and you use private IP addresses on the LAN, go to
WAN
Configuration
> ATM PVC > Setup the ATM PVC Interface
page. Make sure that
Enable network address
Translation (NAT)
is checked.
±
Check the IP settings:
Go to LAN Configuration > IP Address page, ensure you specify IP address on Public IP Address field.
Or go to WAN Configuration > ATM PVC > Setup the ATM PVC Interface page, ensure you specify IP address
on Specified Local WAN IP address field
±
Check the physical connection between the ADSL Router and the LAN.
If the LAN LED on the front panel is off or keeps blinking, there may be problem on the cable connecting to the
ADSL Router.
At the DOS prompt, ping the IP address of the ADSL Router, e.g, ping 192.168.100.100. If the following
response occurs:
Relay from 192.168.100.100 bytes=32 time=100ms TTL=253
Then the connection between the ADSL Router and the network is OK.
If you get a failed ping with the response of:
Request time out
Then the connection is fail. Check the cable between the ADSL Router and the network.
±
Check the DNS setting of the ADSL Router.
At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your DNS IP is
168.95.1.1, then ping 168.95.1.1. If the following response occurs:
Relay from 168.95.1.1 bytes=32 time=100ms TTL=253
Then the connection to the DNS is OK.
