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 
WLAN and LAN

Select this check box to forward NetBIOS packets from the WLAN to the LAN and 
from the LAN to the WLAN. 
Clear this check box to block all NetBIOS packets going from the LAN to the WLAN 
and from the WLAN to the LAN.

Allow between 
WLAN and WAN 
1

Select this check box to forward NetBIOS packets from the WLAN to WAN 1 and 
from WAN 1 to the WLAN. 
Clear this check box to block all NetBIOS packets going from the WLAN to WAN 1 
and from WAN 1 to the WLAN.

Allow between 
WLAN and WAN 
2

Select this check box to forward NetBIOS packets from the WLAN to WAN 2 and 
from WAN 2 to the WLAN. 
Clear this check box to block all NetBIOS packets going from the WLAN to WAN 2 
and from WAN 2 to the WLAN.

Allow between 
WLAN and DMZ

Select this check box to forward NetBIOS packets from the WLAN to the DMZ and 
from the DMZ to the WLAN. If your firewall is enabled with the default policy set to 
block WLAN to DMZ traffic and DMZ to WLAN traffic, you also need to configure 
WLAN to DMZ and DMZ to WLAN firewall rules that forward NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the WLAN to the 
DMZ and from the DMZ to the WLAN.
