Overview

Dial-in

The Internet Gateway's dial-in feature allows remote users to:

For additional security, the dial-back function can be used. In this situation, the Internet Gateway will hang-up the user's incoming connection, and then call them back.

To use the Dial-in Feature:

  1. The relevant port (the one dialed by the remote users) must be configured for dial-in operation. See Dial-in Port Screen for details.
  2. User access data is required. The options are as follows:
  3. The remote user can use the same dial-up software they use for Internet access. They should check the following:
  4. Once connected,the remote user can access LAN resources as they normally would. They will appear to other LAN devices as a normal PC on the LAN, using the IP Address allocated by the Internet Gateway.
If you wish, you can reserve a port for Dial-in access by disabling "Internet Access" from the Internet menu option.

Dial-In

Enable Dial-in

If checked, this port is available for dial-in access. Otherwise, any attempt to dial-in will be blocked.

Disconnect after Idle Time

If a dial-in connection remains inactive, it is terminated after this time period. Allowable range is 0-99 minutes; 0 means no limit.

Dial-in PPP Link

Select the desired security option for log-in:

  • PAP has widespread support; almost all communications systems support it.
  • CHAP is more secure than PAP; the password is encrypted before transmission. If it is selected, the dial-in clients must also support CHAP in order to connect.
  • MS CHAP is the Microsoft version of CHAP, used on Windows platforms. If all dial-in clients are using Windows 95 or later, you can choose this option.
  • None means no checking is performed.

Warning!
If you choose "None", no User Name/Password authentication is performed on dial-in. Anyone can connect; this is a major security risk.
