Motorola WR850GP manual Field Description Operation Mode, Firewall

Configuration	Section 3
Field	Description
Operation Mode:	• Dynamically assigning IP addresses to devices on your local
(continued)	network, simplifying network set-up, using the Dynamic Host
	Configuration Protocol (DHCP).
	This is the WR850’s built-in local area network DHCP server
	(which is configured on the LAN Page).
	• Routing and/or filtering data based on the protocol used
	and/or its content, protecting your broadband connection and
	your local network from undesired access.
	This is the WR850’s built-in firewall (which can be configured
	with specific filters on the FILTERS Page, and with specific
	routing “rules” on the ROUTING Page).
	If all of these router functions are disabled, the WR850 simply
	operates as a combination of a wireless access point and a wired
	5-port Ethernet switch (the physical port labeled “WAN” becomes the
	fifth “switched” port, along with the four “LAN” ports).
	With router functions disabled, all WR850 configuration options that
	use the IP addresses of local network devices are disabled (with any
	entries into those fields ignored). However, all WR850 configuration
	options that use Media Access Control (MAC) addresses of local
	network devices – physical addresses uniquely assigned by
	manufacturers to any network device -- are still available.
	• Selecting Router enables router functions.
	• Selecting Access Point disables router functions.
	NOTE: If you wish to enable some router functions and not all, select
	Router and then disable specific router functions via their
	respective configuration options that follow.
	For example, if you wish to use the firewall but have no need for
	the DHCP server, select Router here and then disable DHCP
	Server on the LAN Page.
	FACTORY DEFAULT: Router
Firewall:	Enables the built-in firewall, to protect your router and local network
(ADVANCED)	from unauthorized access from the Internet.
	• Selecting Enabled engages the built-in firewall.
	• Selecting Disabled disengages the built-in firewall.
	NOTE: It is recommended that the firewall be disabled only if you are
	using alternative firewall protection software.
	NOTE: Firewall is greyed out to Disabled if Operation Mode (above) is
	set to Access Point.
	FACTORY DEFAULT: Enabled
