DESCRIPTION
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.
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.
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.
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 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.
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.
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.
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.
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.
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.
