By default, every time a NetWare Link/PPP outbound call is configured, the authentication information for that outbound call is also entered into the inbound authentication database for the selected interface. The reason is that connectivity between systems is usually bidirectional. For example, if you need to call system X, chances are great that system X also needs to call you. If the same password is used by both systems, you do not need to configure the information for the outbound and inbound authentication entries separately.
You can specify that outbound authentication should match its information with inbound authentication. This causes an inbound authentication entry to be made with the remote system ID and password entered for the WAN call destination. If a group is selected, the database for each interface in the group is updated. If you change either the remote system ID or the password in a WAN call destination, and that remote system ID was previously added to the authentication database, you are prompted to determine whether it will be added to the inbound authentication database.
NOTE: Disable Inbound Authentication Update for a more secure method of authentication. This way, the inbound authentication information is not created or updated automatically for a WAN connection and its related interface, enabling you to maintain the inbound and outbound authentication entries separately.
To configure matching inbound and outbound authentication, complete the following steps:
Load NIASCFG, then select the following parameter path:
Select Configure NIAS > Protocols and Routing > WAN Call Directory
Select a configured WAN call destination.
The PPP Call Destination Configuration menu is displayed.
Select Special Options .
Select Inbound Authentication Update , then select Enabled from the pop-up menu and press Enter .
Press Esc to return to the Internetworking Configuration menu; save your changes when prompted.
If you want these changes to take effect immediately, select Reinitialize System.
If you want to configure other parameters, do so now, then reinitialize the system when you are finished.
