immediately. This mode also supports the Max Idle Time function as Connect
on Demand mode. The Internet connection can be disconnected automatically
after a specified inactivity period (Max Idle Time) and not be able to re-establish
when you attempt to access the Internet again.
• Authentication Type - Choose an authentication type.
Note:
• Sometimes the connection cannot be terminated although you have specified the Max Idle Time because
some applications are visiting the Internet continually in the background.
If you want to do some advanced configurations, please click Advanced.
• Service Name/Server Name - The service name and server name should not be
configured unless you are sure it is necessary for your ISP. In most cases, leaving
these fields blank will work.
• MTU (Bytes) - The default MTU size is 1480 bytes. It is not recommended that you
change the default MTU size unless required by your ISP.
• Enable IGMP Proxy - IGMP (Internet Group Management Protocol) is used to manage
multicasting on TCP/IP networks. Some ISPs use IGMP to perform remote configuration
for client devices, such as the modem router. The default value is enabled, and if you
are not sure, please contact your ISP or just leave it.
• ISP Specified IP Address - If your ISP does not automatically assign IP addresses to
the router, please select Use IP address specified by ISP and enter the IP address
provided by your ISP in dotted-decimal notation.
• Detect Online Interval - The router will detect Access Concentrator online at every
interval. The default value is 0. You can input the value between 0 and 120. The value
0 means no detect.
