LABEL DESCRIPTION
WAN Priority
WAN2 Priority
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 (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").
Active Select this check box to have the device use traffic redirect if the normal WAN
connection goes down.
Backup
Gateway IP
Address 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.
Fail Tolerance Type the number of times the device may attempt and fail to connect to the Internet
before traffic is forwarded to the backup gateway.
Period (sec) 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.
Timeout (sec) Type the number of seconds for the device to wait for a ping response 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.
Windows
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
WAN1 and LAN 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.
Allow between
WAN1 and
DMZ 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.
Allow between
WAN1 and
WLAN 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.
Allow between
WAN2 and LAN Select this check box to forward NetBIOS packets from the WAN2 port to the LAN
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.
