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 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.
Clear this check box to block all NetBIOS packets going from the LAN to the WAN 

and from the WAN to the LAN.
