LABEL DESCRIPTION
Route Priority
WAN
Traffic Redirect
Dial Backup The default WAN connection is "1' as your broadband connection via the WAN port
should always be your preferred method of accessing the WAN. The default priority
of the routes is WAN, Traffic Redirect and then Dial Backup:
You have two choices for an auxiliary connection (Traffic Redirect and Dial
Backup) in the event that your regular WAN connection goes down. If Dial Backup
is preferred to Traffic Redirect, then type "14" in the Dial Backup Priority (metric)
field (and leave the Traffic Redirect Priority (metric) at the default of "15").
The Dial Backup field is available only when you enable the corresponding dial
backup feature in the Dial Backup screen.

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.
Allow between
WAN and LAN
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.
Allow between
WAN and DMZ
Select this check box to forward NetBIOS packets from the WAN to the DMZ and
from the DMZ to the WAN.
Clear this check box to block all NetBIOS packets going from the WAN to the DMZ
and from the DMZ to the WAN.
