•
Always on:
A connection to the Internet is always maintained.
•
On demand:
A connection to the Internet is made as needed.
•
Manual:
You have to open up the Web-based management interface and click the
Connect button manually any time that you wish to connect to the Internet.
Maximum Idle Time:
Time interval the machine can be idle before the PPTP connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" connection
mode.
L2TP
L2TP (Layer Two Tunneling Protocol) uses a virtual private network to connect to your ISP.
This method of connection requires you to enter a
Username
and
Password
(provided by
your Internet Service Provider) to gain access to the Internet. The ISP provides the values for
L2TP IP Address
,
L2TP Subnet Mask
,
L2TP Gateway IP Address
, and
L2TP Server IP
Address
(may be the same as the gateway).
Reconnect Mode:
Typically L2TP connections are not always on. The Wireless router allows
you to set the reconnection mode. The settings are:
•
Always on:
A connection to the Internet is always maintained.
•
On demand:
A connection to the Internet is made as needed.
•
Manual:
You have to open up the Web-based management interface and click the
Connect button manually any time that you wish to connect to the Internet.
Maximum Idle Time:
Time interval the machine can be idle before the L2TP connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" connection
mode.
Advanced
These options apply to all WAN modes.
Use These DNS Servers:
This option should be enabled if your ISP requires you to enter the
DNS Server information. You will then be able to enter a primary and secondary DNS server.
Use the default MTU:
If this option is checked (the default case), the router selects the usual
MTU settings for the type of WAN interface in use. If this option is unchecked, the router uses
the value of the MTU option (which follows).
MTU:
The Maximum Transmission Unit (MTU) is a parameter that determines the largest
packet size (in bytes) that the router will send to the WAN. If LAN devices send larger packets,
the router will break them into smaller packets. Ideally, you should set this to match the MTU of
the connection to your ISP. Typical values are 1500 bytes for an Ethernet connection and 1492
bytes for a PPPoE connection. If the router's MTU is set too high, packets will be fragmented
downstream. If the router's MTU is set too low, the router will fragment packets unnecessarily
and in extreme cases may be unable to establish some connections. In either case, network
performance can suffer.
WAN Port Speed:
Normally, this is set to "auto". If you have trouble connecting to the WAN, try
the other settings.
Respond to WAN Ping:
If you leave this option unchecked, you are causing the public WAN
