NBG410W3G Series User’s Guide

This table allows you to assign IP addresses on the LAN to specific individual computers 
based on their MAC Addresses. 
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address 
is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 
00:A0:C5:00:00:02.
To change your ZyXEL Device’s static DHCP settings, click NETWORK > LAN > Static 
DHCP. The screen appears as shown.

DHCP WINS 

Server 1, 2

Type the IP address of the WINS (Windows Internet Naming Service) server that 

you want to send to the DHCP clients. The WINS server keeps a mapping table of 

the computer names on your network and the IP addresses that they are currently 

using.  

Windows 

Networking 

(NetBIOS over 

TCP/IP)

NetBIOS (Network Basic Input/Output System) are TCP or UDP 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 WAN1

Select this check box to forward NetBIOS packets from the LAN to WAN 1and from 

WAN 1 to the LAN. If your firewall is enabled with the default policy set to block 

WAN 1 to LAN traffic, you also need to enable the default WAN 1 to LAN firewall 

rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to WAN 1 

and from WAN 1 to the LAN.

Allow between 

LAN and WAN2

Select this check box to forward NetBIOS packets from the LAN to WAN 2 and 

from WAN 2 to the LAN. If your firewall is enabled with the default policy set to 

block WAN 2 to LAN traffic, you also need to enable the default WAN 2 to LAN 

firewall rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to WAN 2 

and from WAN 2 to the LAN.

Allow between 

LAN and DMZ

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

from the DMZ to the LAN. If your firewall is enabled with the default policy set to 

block DMZ to LAN traffic, you also need to enable the default DMZ to LAN firewall 

rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the DMZ 

and from the DMZ to the LAN.
