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.

Allow between 
LAN and WLAN

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