IGMP Proxy Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a Multicast group – it is not used to carry user data.

to a single IP address and port on the external network. The Zyxel Device also maps packets
coming to that external IP address and port to the internal IP address and port.
