Chapter 7 WAN Screens

Figure 54   WAN Route

The following table describes the labels in this screen.

Table 36   WAN Route 

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.
