IGMP Proxy

IP hosts use Internet group management protocol (IGMP) to report their multicast group

memberships to neighboring routers. Similarly, multicast routers use IGMP to discover

which of their hosts belong to multicast groups. Your router supports IGMP proxy that

handles IGMP messages. When enabled, your router acts as a proxy for a LAN host

making requests to join and leave multicast groups, or a multicast router sending

multicast packets to multicast groups on the WAN side.

Multicasting is a form of limited broadcast. UDP is used to send datagrams to all hosts

that belong to what is called a Host Group. A host group is a set of one or more hosts

identified by a single IP destination address. The following statements apply to host

groups:

°

Anyone can join or leave a host group at will.

°

There are no restrictions on a host’s location.

°

There are no restrictions on the number of members that may belong to a host

group.

°

A host may belong to multiple host groups.

Non-group members may send UDP datagrams to the host group.

Multicasting is useful when the same data needs to be sent to more than one device. For

instance, if one device is responsible for acquiring data that many other devices need,

then multicasting is a natural fit. Note that using multicasting as opposed to sending the

same data to individual devices uses less network bandwidth. The multicast feature also

enables you to receive multicast video streams from multicast servers.

The IGMP Proxy page allows you to enable multicast on available WAN and LAN

connections. You can configure the WAN or LAN interface as one of the following:

°

Upstream

Upstream

Upstream

Upstream The interface that IGMP requests from hosts are sent to the multicast

router.

°

Downstream

Downstream The interface data from the multicast router are sent to hosts in the

multicast group database.

Ignore No IGMP request nor data multicast are forwarded.

You can perform one of the two options:

1. Configure one or more WAN interface as the upstream interface.

2. Configure one or more LAN interface as the upstream interface.

TR-068 WAN Access

The TR-068 WAN Access page enables you to give temporary permission to someone

(such as technical support staff) to be able to access your router from the WAN side.

From the moment the account is enabled the user is expected to log in within 20

minutes, otherwise the account expires. Once the user has logged in, if the session

remains inactive for more than 20 minutes, the user will be logged out and the account

expires.

Dynamic DNS Client

Dynamic DNS allows the user to register with a Dynamic DNS Provider. The Dynamic DNS

will be linked with the WAN IP of the router even after the ISP update the WAN IP to

another IP address. It can be useful in web hosting and FTP services.
