Chapter 5 Device Network Settings The following table describes the fields in this screen. Table 17 Device Operation > Device Configuration > Network > WAN > General (ZyNOS ZyWALL) 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. Allow between WAN1 and DMZ Allow between WAN1 and WLAN 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. Vantage CNM User's Guide 67
