DNS

If the radio button Automatically obtain from server is selected, the DNS (Domain Name Server) address will be

obtained automatically from your ISP server.

To use a fixed IP address, select Use this DNS and enter the IP address of the DNS (Domain Name Server) you

wish to use.

Backup DNS

If the DNS is unavailable, the "Backup DNS" servers configured here will be used.

MTU

MTU (Maximum Transmission Unit) value should only be changed if advised to do so by Technical Support.

Enter a value between 500 and 1492.

This device will still auto-negotiate with the remote server, to set the MTU size. The smaller of the 2 values (auto-

negotiated, or entered here) will be used.

For direct connections (FixIP/DHCP), the MTU used is always 1500.

If your ISP does not use a login method (username, password) for Internet access, leave this

at the default value FixIP/DHCP. Otherwise, check the documentation from your ISP,

select the login method used, and enter the required data.

PPPoE - this is the most common login method, widely used with DSL modems. Normally,

your ISP will have provided some software to connect and login. This software is no

longer required, and should not be used.

Connection

Behavior

Select the desired option:

• Keep alive (maintain connection) The connection will never be disconnected by

this device. If disconnected by your ISP, the connection will be re-established

immediately. (However, this does not ensure that your Internet IP address will

remain unchanged.)

• Automatic Connect/Disconnect An Internet connection is automatically made

when required, and disconnected when idle for the time period specified by the

"Auto-disconnect Idle Time-out".

• Manual Connect/Disconnect You must manually establish and terminate the

connection.
