D-Link DSL-2740B manual UPnP, Igmp Snooping

	DSL-2740B Wireless ADSL Router User Guide
Parameters		Description
UPnP		UPnP supports zero-configuration networking and automatic discovery
		for many types of networked devices. When enabled, it allows other
		devices that support UPnP to dynamically join a network, obtain an IP
		address, convey its capabilities, and learn about the presence and
		capabilities of other devices. DHCP and DNS service can also be used if
		available on the network. UPnP also allows supported devices to leave a
		network automatically without adverse effects to the device or other
		devices on the network.
IGMP Snooping		IGMP snooping is a feature that allows the layer-2 device (switch) to
		"listen in" on the IGMP conversation between hosts and routers. By
		doing so, this device can forwards the multicast packets to the hosts
		which have joined the multicast group, instead of flooding to all hosts.
		Standard Mode: Listen and forward
		Blocking Mode: Listen and block
DHCP		The DHCP server is enabled by default for the Router’s Ethernet LAN
		interface. DHCP service will supply IP settings to workstations configured
		to automatically obtain IP settings that are connected to the Router
		though the Ethernet port. When the Router is used for DHCP it becomes
		the default gateway for DHCP client connected to it. Keep in mind that if
		you change the IP address of the Router the range of IP addresses in
		the pool used for DHCP on the LAN will also be changed. The IP address
		pool can be up to 253 IP addresses.

To manually configure IP settings on Windows workstations, open the TCP/IP Properties menu and select the “Use the following IP address” option. You will need to supply the IP addres, Subnet mask and Defualt

Note gateway (use IP address of DSL- 2740B) for each workstation. The example here also uses manually configured DNS settings.
