5.3.1 WAN1 (ZyNOS ZyWALL with one WAN port)
The screen differs by the encapsulation type chosen.
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.

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.
