Isdn Dial-In Parameters Panel - Nortel BCM50 Configuration Manual

518 Chapter 70 Dial Up Interfaces panel
If you want DIALIN_PC to access PC1 (192.168.1.50) on the customer LAN, then you must
configure a static route on the integrated router to route all traffic for the dial-in IP address to the
CSC card on the BCM50 (192.168.1.2). The static route is configured as shown in
Table 117 Static route configuration

You must also configure the firewall on the integrated router to Bypass Triangle Route. Using the
same example, if there is a ping request from DIALIN_PC (10.10.14.2) to PC1 (192.168.1.50):
• The CSC receives the ping request at 10.10.14.1 and forwards the packet through the customer
LAN (192.168.1.2) to PC1 (192.168.1.50).
• PC1 sends the ping reply to the integrated router (192.168.1.2) since this is the default gateway
for PC1. PC1 does not have a route to 10.10.14.2.
• If Bypass Triangle Route is not selected, the firewall blocks the ping reply and generates the
error message: out-of-order ICMP. This occurs because the integrated router does not see the
ping request. The ping request was sent directly from the CSC (192.168.1.2) to PC1
(192.168.1.50).
For more information about configuring static routes and configuring Bypass Triangle Route, see
BCM50a Integrated Router Configuration — Basics (N0115790) or BCM50e Integrated Router
Configuration — Basics (N0115788).

ISDN Dial-In Parameters panel

The ISDN Dial-In Parameters controls Dial-in to the BCM for remote access. This panel is used to
configure the ISDN for Dial-in. It also displays the connection status of the ISDN connections if
any are in progress. Refer to
