IGMP/ALG/Passthrough
On the Advanced / IGMP/ALG/Passthrough page, you can allow the router to use IGMP and
RTSP, enable the SIP ALG and PPPoE/PPTP/L2TP/IPsec pass through functions.
IGMP is used for managing multicast traffic (transferring data to a group of destinations). This
protocol allows using network resources for some applications, e.g., for streaming video, more
efficiently.
SIP is used for creating, modifying, and terminating communication sessions. This protocol allows
telephone calls via the Internet.
RTSP is used for real-time streaming multimedia data delivery. This protocol allows some
applications to receive streaming audio/video from the Internet.
The PPPoE pass through function allows PPPoE clients of computers from your LAN to connect to
the Internet through PPPoE connections of the router.
The PPTP pass through, L2TP pass through and IPsec pass through functions allow VPN PPTP,
L2TP and IPsec traffic to pass through the router so that clients from your LAN can establish
relevant connections with remote networks.
