Chapter 9 WAN Screens Table 35 NETWORK > WAN > General (continued) LABEL DESCRIPTION Check Fail Tolerance Type how many WAN connection checks can fail (1-10) before the connection is considered "down" (not connected). The ZyWALL still checks a "down" connection to detect if it reconnects. Check WAN1/2 Connectivity Select the check box to have the ZyWALL periodically test the respective WAN interface's connection. Select Ping Default Gateway to have the ZyWALL ping the WAN interface's default gateway IP address. Select Ping this Address and enter a domain name or IP address of a reliable nearby computer (for example, your ISP's DNS server address) to have the ZyWALL ping that address. For a domain name, use up to 63 alphanumeric characters (hyphens, periods and the underscore are also allowed) without spaces. Check Traffic Redirection Connectivity Select the check box to have the ZyWALL periodically test the traffic redirect connection. Select Ping Default Gateway to have the ZyWALL ping the backup gateway's IP address. Select Ping this Address and enter a domain name or IP address of a reliable nearby computer (for example, your ISP's DNS server address) to have the ZyWALL ping that address. For a domain name, use up to 63 alphanumeric characters (hyphens, periods and the underscore are also allowed) without spaces. 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 WAN 1 to the LAN port and from the LAN port to WAN1. If your firewall is enabled with the default policy set to block WAN 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 WAN 1 to the LAN port and from LAN port to WAN1. Allow between WAN1 and DMZ Select this check box to forward NetBIOS packets from WAN 1 to the DMZ port and from the DMZ port to WAN1. Clear this check box to block all NetBIOS packets going from WAN 1 to the DMZ port and from DMZ port to WAN1. Allow between WAN1 and WLAN Select this check box to forward NetBIOS packets from WAN 1 to the WLAN port and from the WLAN port to WAN 1. Clear this check box to block all NetBIOS packets going from WAN 1to the WLAN port and from WLAN port to WAN1. Allow between WAN2 and LAN Select this check box to forward NetBIOS packets from WAN 2 to the LAN port and from the LAN port to WAN2. If your firewall is enabled with the default policy set to block WAN 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 WAN 2 to the LAN port and from LAN port to WAN2. Allow between WAN2 and DMZ Select this check box to forward NetBIOS packets from WAN 2 to the DMZ port and from the DMZ port to WAN2. Clear this check box to block all NetBIOS packets going from WAN 2 to the DMZ port and from DMZ port to WAN2. Allow between WAN1 and WLAN Select this check box to forward NetBIOS packets from WAN 2 to the WLAN port and from the WLAN port to WAN 2. Clear this check box to block all NetBIOS packets going from WAN 2 to the WLAN port and from WLAN port to WAN 2. 176 ZyWALL 5/35/70 Series User's Guide
