	Active	Select this if you want to let computers on different subnets use the
		NBG-460N.

	Windows Networking (NetBIOS over TCP/IP): NetBIOS (Network Basic Input/Output
	System) are TCP or UDP broadcast packets that enable a computer to connect to and
	communicate with a LAN. For some dial-up services such as PPPoE or PPTP, NetBIOS
	packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS
	packets to pass through to the WAN in order to find a computer on the WAN.

	Allow between LAN	Select this check box to forward NetBIOS packets from the LAN to
	and WAN	the WAN and from the WAN to the LAN. If your firewall is enabled
		with the default policy set to block WAN to LAN traffic, you also
		need to enable the default WAN to LAN firewall rule that forwards
		NetBIOS traffic.
		Clear this check box to block all NetBIOS packets going from the
		LAN to the WAN and from the WAN to the LAN.

	Apply	Click Apply to save your changes back to the NBG-460N.

	Reset	Click Reset to begin configuring this screen afresh.

9.7 Technical Reference

The following section contains additional technical information about the NBG- 460N features described in this chapter.

Refer to Section 8.3.2 on page 135 for information on Multicast.

9.7.1 LANs, WANs and the ZyXEL Device

The actual physical connection determines whether the NBG-460N ports are LAN or WAN ports. There are two separate IP networks, one inside the LAN network and the other outside the WAN network as shown next.
