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 and WAN Select this check box to forward NetBIOS packets from the LAN to 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.

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

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.
