Configuring Allowed Networks

Allowed networks are the source of IP multicast traffic. You can configure your
router to allow IP multicast traffic from certain networks to pass through. IP
multicast traffic from other networks is dropped.
By default, the RV220W only forwards multicast packets that originate in its
immediate WAN. However, you can configure the router to allow IP multicast traffic
from other networks to also pass through. Multicast traffic originating in networks
not specified in the list of allowed networks is dropped by the router.
To configure allowed networks:
Choose Networking > LAN > IGMP Configuration.
The Allowed Networks Table lists all allowed networks configured for the
RV220W. Click Add to add a new network, or Edit to edit an existing network.
Enter the network address from which the multicast packets originate.
Enter the mask length for the network address.
Use the mask length to designate the subnet mask for the allowed network. For
example, 16 represents 255.255.0.0 and 24 represents 255.255.255.0.
Click Save.

Configuring Jumbo Frame Support

A standard Ethernet frame contains 1,500 bytes of data. Enabling the Jumbo
Frames feature allows the switch to send jumbo frames within the LAN containing
up to 9,000 bytes of data per frame.
You can configure the RV220W to support jumbo frames. After support is enabled,
devices on the LAN side of the network can exchange traffic that contains jumbo
frames. To configure jumbo frames:
Choose Networking > LAN > Jumbo Frames.
Check the Enable box.
Click Save.
