D-Link DVA-G3340S manual Default Route, Firewall, IP Control

	The Maximum Transmission Unit size may be
	changed if you want to optimize efficiency for
	uploading data through the WAN interface. The
	default setting (1400 bytes) should be suitable for
MTU	most users. Some user may want to adjust the
	setting to optimize performance for wireless traffic or
	when low latency is desired (such as with Internet
	gaming). It is highly recommended that the user
	research how adjusting the MTU may affect network
	traffic for better or worse.
	Similar to the MTU, except this applies to Maximum
	Received Unit size for downloading data. Most users
	will be happy with the default setting (1492 bytes).
	However this may also be optimized for fast
MRU	downloads of general bulk Internet traffic, for low
	latency or for downloading to computers on the
	Wireless LAN. As with the MTU setting, the user
	should carefully consider how changing the MRU may
	effect Internet downloads for all systems on your
	LAN.
	When this is enabled, the Router will be considered
	to be the primary gateway to the Internet and WAN
Default Route	for systems on your network. If you are using the
	Router on a network with one or more alternative
	gateway routers, you may prefer to disable this if
	you will use another router as the primary gateway.
	Network Address Translation may be enabled or
	disabled with the pull-down menu. Keep in mind that
	disabling NAT allows only a single computer to be
NAT	used for Internet access through the Router. NAT is
	enabled for the Router on all connections (i.e. Pvc0 –
	Pvc7) if your Router is set up for multiple virtual
	connections.
	Use this to universally enable or disable the Firewall
	and Filter features available in the Router. If you
Firewall	disable this you will not be able to configure settings
	in the Firewall or Filters menus in the Advanced
	directory.
	This is used to determine how global IP settings are
	handled for the WAN interface. Typically PPPoE or
IP Control	PPPoA connections will use the default setting for
	Dynamic IP. Some users will be given a specific IP
	address for the WAN interface. In this case you need
	to change this setting to Static IP. When Static IP is
	selected in the IP Control menu, you need to type in
