**MulticastIP** and **MulticastPortNo** is a multicast address for GWSEARCH messages. Gateway is waiting GWSEARCH and when receiving it send GWINFO message via MulticastIP address. Clients can get the gateway address (Gateway IP address and **GatewayPortNo**) from GWINFO message by means of std::recvfrom().
Client should know the MulticastIP and MulticastPortNo to send a SEARCHGW message.
**GatewayId** is used by GWINFO message.
