DI-304/DI-304M ISDN Remote Router
♦Dial-In Service – Click Enable to allow dial-in service. Note that if you click Disable, the router will not accept any in-coming ISDN calls.
PPP/MP Setup
♦Dial-In PPP Authentication – There are two choices:
◊PAP - Selecting this option will force the router to authenticate dial-in users with the PAP protocol.
◊PAP or CHAP - Selecting this option means the router will attempt to authenticate dial-in users with the CHAP protocol first. If the dial-in user does not support this protocol, it will fall back to use the PAP protocol for authentication.
♦Mutual Authentication (PAP) – Enable this only if the connecting router requires mutual authentication. By default, the option is set to No.
♦Username – Enter the mutual Authentication username.
♦Password – Enter the mutual Authentication password.
IP Address Assignment for Dial-In Users
♦Start IP Address – Enter a start IP address to be assigned to the dial-in PPP connection. You should choose an IP address from the local private network. For example, if the local private network is 192.168.1.0/255.255.255.0, you can choose 192.168.1.200 to be the Start IP Address. Because one ISDN BRI has two independent data channels (B-channels), it is possible to allow two dial-in users at the same time. The first dial-in user would be assigned the start IP address and the second would be assigned the start IP address plus 1. Click OK.
Creating an Access Account for a Dial-in User
After activating the dial-in capability, you must create an access account for each dial-in user. From the Advanced Setup menu, click Remote Dial-In User Setup to open the page shown below. The router provides 10 access accounts for dial-in users.
