proxying is disabled. If you clear the check box, IGMP proxying is enabled and
you can select which type of IGMP messages are forwarded by the router:
-
Auto: The router automatically detects the supported protocol (IGMPv3 or
IGMPv2) and forwards the message accordingly. This is the default setting,
which we recommend.
-
IGMPv3: The router forwards IGMPv3 messages but can also forward IGMPv2
messages. (IGMPv3 is backward compatible with IGMPv2.).
-
IGMPv2: The router forwards IGMPv2 messages
only
and ignores IGMPv3
messages.
If you do not need this feature, select the check box to disable it.

MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Change
the MTU only if you are sure that it is necessary for your ISP connection. See MTU
size on page 54.
•
NAT Filtering. Network Address Translation (NAT) determines how the router
processes inbound traffic. Secured NAT protects computers on the LAN from
attacks from the Internet, but might prevent some Internet games, point-to-point
applications, or multimedia applications from working. Open NAT provides a
much less secured firewall, but allows almost all Internet applications to work.
•
Disable SIP ALG. The application-level gateway (ALG) for the Session Initiation
Protocol (SIP) is enabled by default for enhanced address and port translation.
However, some types of VoIP and video traffic might not work well when the SIP
ALG is enabled. For this reason, the router provides the option to disable the SIP
ALG.

Change the WAN port speed
The router's WAN port supports Ethernet speeds up to 2.5 Gbps. The router's LAN
Ethernet ports 2–5 support Ethernet speeds up to 1 Gbps.
If your modem supports Internet connection speeds up to 1 Gbps only, you can set the
router's LAN port 2 as the WAN port and connect your modem to LAN port 2. The WAN
port now acts as a LAN port that operates at 2.5 Gbps.
You can then connect your satellite to your router using an Ethernet backhaul connection.
To set up the Ethernet backhaul connection, use an Ethernet cable to connect the
