DESCRIPTION
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 (dial backup does not apply to all device models):
You have two choices for an auxiliary connection 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").
Select this check box to have the device use traffic redirect if the normal
WAN connection goes down.
Type the IP address of your backup gateway in dotted decimal notation.
The device automatically forwards traffic to this IP address if the device's
Internet connection terminates.
Type the number of times the device may attempt and fail to connect to
the Internet before traffic is forwarded to the backup gateway.
Type the number of seconds for the device to wait between checks to see
if it can connect to the WAN IP address (Check WAN IP Address field)
or default gateway. Allow more time if your destination IP address
handles lots of traffic.
from the IP Address in the Check WAN IP Address field before it times
out. The WAN connection is considered "down" after the device times out
the number of times specified in the Fail Tolerance field. Use a higher
value in this field if your network is busy or congested.
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.
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.
Clear this check box to block all NetBIOS packets going from the WAN1
port to the LAN port and from LAN port to WAN1.
Select this check box to forward NetBIOS packets from the WAN1 port to
the DMZ port and from the DMZ port to WAN1.
Clear this check box to block all NetBIOS packets going from the WAN1
port to the DMZ port and from DMZ port to WAN1.
Select this check box to forward NetBIOS packets from the WAN1 port to
the WLAN port and from the WLAN port to WAN1.
Clear this check box to block all NetBIOS packets going from the WAN1
port to the WLAN port and from WLAN port to WAN1.
