Manage Multicast Pass-Through
Multicast pass-through is supported for IPv4 traffic only. The following sections provide
information about managing multicast pass-through:
• Multicast Pass-Through
• Enable and Configure Multicast Pass-Through
• Remove One or More Multicast Source Addresses
Multicast Pass-Through
IP multicast pass-through allows multicast packets that originate in the WAN, such as packets
from a media streaming or gaming application, to be forwarded to the LAN subnet. Internet
Group Management Protocol (IGMP) is used to support multicast between IP hosts and their
adjacent neighbors.
If you enable multicast pass-through, an IGMP proxy is enabled for the upstream (WAN) and
downstream (LAN) interfaces. This proxy allows the VPN firewall to forward relevant
multicast traffic from the WAN to the LAN and to keep track of the IGMP group membership
when LAN hosts join or leave the multicast group.
Enable and Configure Multicast Pass-Through
The following procedure describes how to enable and configure multicast pass-through for
IPv4 traffic. By default, multicast pass-through is disabled.
To enable and configure multicast pass-through:
1. On your computer, launch an Internet browser.
2. In the address field of your browser, enter the IP address that was assigned to the VPN
firewall during the installation process.
The VPN firewall factory default IP address is 192.168.1.1.
The NETGEAR Configuration Manager Login screen displays.
3. In the Username field, type your user name and in the Password / Passcode field, type
your password.
For the default administrative account, the default user name is admin and the default
password is password.
4. If you changed the default domain or were assigned a domain, from the Domain menu,
select the domain.
