services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls.
Select this check box to forward NetBIOS packets from the WAN1 port to the LAN
port and from the LAN port to WAN1. If your firewall is enabled with the default
policy set to block WAN port 1 to LAN traffic, you also need to enable the default
WAN1 to LAN firewall rule that forwards NetBIOS traffic.

port and from the LAN port to WAN2. If your firewall is enabled with the default
policy set to block WAN port 2 to LAN traffic, you also need to enable the default
WAN2 to LAN firewall rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the WAN2 port to the
LAN port and from LAN port to WAN2.
Select this check box to forward NetBIOS packets from the WAN2 port to the DMZ
port and from the DMZ port to WAN2.
Clear this check box to block all NetBIOS packets going from the WAN2 port to the
DMZ port and from DMZ port to WAN2.
