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:

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 Table 118 for a description of the ISDN Dial-in fields. If the BCM50

has an integrated router (BCM50a or BCM50e), see “Additional configuration to allow network

access functionality” on page 517.
