Connection 
Detection Host 
If you choose PING/HTTP as Connection Detection Mode, 
you have to specify the detection host address in this field. 
Use the default setting. 
Add – Click this button to have a field for adding a new IP 
address. Assign an IP address or Domain name as a 
destination to be detected whether the host is active (sending 
reply to the router) or not. If not, the connection of WAN 
interface will be regarded as breaking down. This function 
is available when Connection Detection Mode is set with 
PING or HTTP. 
Save – Click this button to save the setting. 
 – Click the icon to remove the selected entry. 
Connection 
Detection Interval 
Assign an interval period of time for each detecting. 
Connection 
Detection Retry 
Assign detecting times to ensure the connection of the WAN 
interface. After passing the times you set in this field and no 
reply received by the router, the connection of WAN 
interface will be regarded as breaking down. 
IP Alias 
Type other IP addresses to be bound to this interface. This 
setting is optional. If you have typed addresses here, you can 
see and choose it in later web page settings (e.g., 
NAT>>Port Redirection/DMZ Host). 
Add – Click this button to display the IP address field for 
adding a new IP address. Type the IP address on the tiny 
boxes one by one. 
Save – After finished the IP address configuration, click 
Save to save the setting onto the router.
