Configuring Dial-in User Parameters 117

7In the ISP Selection field, select the service providers that this dial-in user can access.

8In the Data Compression field, choose to have data compression active or inactive. By default compression is disabled. (In order for compression to occur, the other end of the connection must also have compression active.)

Callback Parameters

This section allows you to enable and configure callback functionality. Callback occurs when, upon a successful connection of dial-in a user, the LAN Modem drops the incoming call and places a return call to the dial-in user. In order for callback to work properly, the client-side device must also have callback active.

To specify your Callback parameters, follow these steps:

1In the Enable Callback field, check to activate Callback for this dial-in user. By default, Callback is disabled.

2In the Callback Telephone Number field, enter the number the LAN Modem will call back when this dial-in user accesses the LAN Modem.

3In the Callback Alternate Number field, enter a second telephone to be used for either Multilink PPP or as a second number to try if the call cannot be established with the first telephone number.

4In the Callback Authentication field, check the box to require callback authentication.

5In the Callback Username field, enter the username used by the server if callback authentication is requested by the client.

6In the Callback Password field, enter the password used by the server if callback authentication is requested by the client.

7In the Callback Delay field, enter the amount of time in seconds to wait until the dial-in user is called back. By default this is set to 10.

WAN Parameters

If you used the Dial-in Wizard to create this Dial-in User profile, these fields should be left as set by the Dial-in Wizard.

1LAN Modem WAN IP: If the local LAN Modem WAN link has a static IP address, enter the WAN static IP address. Otherwise leave these fields as set by the Dial-in Wizard. If you are using the Advanced dial-in scenario, enter the IP address of the LAN Modem which is receiving the dial-in call.

2Remote LAN IP: If the remote site of the WAN link has a static IP address, enter the WAN static IP address. Otherwise, leave these fields as set by the Dial-in Wizard. For the Advanced dial-in scenario, enter the IP address of the router which is dialing into the LAN Modem.

3Remote LAN Subnet Mask: If the remote site of the WAN link has a static IP address, enter the subnet mask of the remote LAN. Otherwise, leave these fields as set by the Dial-in Wizard. If you are using the Advanced dial-in scenario, enter the subnet mask of the remote LAN.

4Enter your Primary and Secondary (optional) DNS address as instructed by your MIS administrator, or as set by the Dial-in Wizard. For the Advanced dial-in scenario, enter the IP address of the LAN Modem which is receiving the dial-in call.
