ALG/Passthrough
On the
Advanced / ALG/Passthrough
page, you can allow the router to use RTSP, enable the
SIP ALG and PPPoE/PPTP/L2TP/IPsec pass through functions, and assign a higher priority for a
specific type of traffic.
Assigning a higher priority for a specific type of traffic allows you to allocate the router's resources
for online games or IPTV services, service packet transmission, or management of the router.
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 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.
