Configuring the AETA LAN port

The LAN port can be used for connecting your LAN to the Internet via ML PPP or PPP. It could also be used for providing a connection between 2 LANs. For further information on different ways the AETA can help you in your business, check out Network Scenarios or the Braintree web site.

Before configuring the Ethernet port using this method, you will need to have configured the Serial or USB port on your PC. You will also need to use a terminal program such as Hyper Terminal to configure the AETA using AT commands.

To configure the Ethernet port with a basic configuration, you will need the following information:  

If you don't feel confident using this method to configure the AETA's LAN port check out Braintree's web site for configuration utilities on the useful links page.

 

Warning:  Programs that periodically access the Internet, such as E-mail programs, if left operating will cause unnecessary calls to your ISP. It is possible to disable or configure the periodic Internet access feature in most programmes, see your software user guide or help for assistance.

If IP packets are sent unnecessarily on your local network that are outside your local IP address range, this will result in excessive calls to your Internet Service Provider. This will result in increased call charges. By design, the AETA only passes TCP/IP packets and will not forward broadcast packets.

Please Note: This is the normal method of operation for Dial On Demand routing equipment.
 

 

The commands to enter are:

    AT*E0="172.168.0.1" replace the italics with you IP address.  Then,

    AT*E1="255.255.255.0" replace the italics with your Network Mask.  Then,

    AT&W (This writes the IP address and mask to the memory)

For the IP address and the Network Mask to take effect it is necessary to reset the AETA. To do this, turn the power off to the AETA for at least 5 seconds.

Warning: Turning the power off to the AETA will temporarily disrupt all communications including EFTPOS and Phone.

Turn the power back on to the AETA.  Then enter:

    AT*E2=180   idle call time out delay in seconds. The inactivity time out delay for Internet traffic will then be set to 180 seconds.

    AT*P0=0198303030 Replace Italics with your ISP phone number or replace the italics with your ISP's ISDN access number.

    AT*P1="User Name" Replace the italics with your User Name for your ISP.

   AT*P2="Password" Replace the italics with your Password for your ISP.

Multilink PPP

Multilink PPP is used to double the available connection speed to the Internet, this can potentially halve the time to download web pages and files from the Internet*.  The AETA does this by making a second call to your Internet Service Provider (ISP) so that two lines are then available for downloading information.  The AETA will make the second call to your ISP depending upon the amount of information you are downloading from the Internet.  By default it will also disconnect the second call to allow an incoming or outgoing phone call.

If your ISP supports Multilink PPP, you may wish it enabled.  Follow the link below for instructions on enabling Multilink PPP.

 

Download times from the Internet vary due to many factors only one of which is the speed you are connected to the Internet. Other factors may include the speed of the server you are connecting to and the speed and bandwidth of any connections between your ISP and the server you are connecting to. 

By default the AETA provides Dynamic Network Address Translation (Dynamic NAT). This provides a level of separation between your LAN and the Internet. Due to the operation of Dynamic NAT, any programs using the FTP protocol will need to use passive mode (PASV).  For information on how Dynamic NAT works, go to http://www.howstuffworks.com/nat.htm.  For a technical reference to NAT, go to rfc3022 (Traditional NAT).
