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