This function encodes information from the SYN packet into the response (SYN/ACK). Despite being a standard technique, enabling this will create some secondary limitations that may not be handled well by some old TCP/IP stacks.

 **Enable quick leave** - This is a feature of IGMP v2. This allows the router to stop the streaming of a multicast to an IP address as soon as that end device sends the quick leave IGMP packet.
-**Custom Configuration** - This option allows you to set up advanced parameters for the IGMP proxy daemon. Please consult the official IGMP documentation before finalizing these settings.\\

-**Force IGMPv2** - IGMPv2 enhances the IGMP communication supporting additional messages/behavior to optimise the end-to-end communication between client and server. Possibly the most important being the "Group Leave" message which is lacking instead in IGMP v1.\\
