Configuring PIX 501 with ISDN DialUp Connection

Unanswered Question

Hi,


I'd really appreciate if someone could help me with the following scenario:


I need to configure the PIX 501 to work in the following network setup



LAN ---> PIX 501 ---> Cisco 760 ISDN Router ---> Internet


The LAN I have is very small, having 11 users on Static IPs, with a WinNT 4 server (LAN's IP range is 192.168.0.x)

The internet connection is a 128Kbps DialUp connection.

We get a Dynamic IP address from the ISP everytime there is a new connection.


Would the PIX firewall work in such a setup? If yes, how do I set up the PIX 501? and do I need to change anything on the Cisco 760?


Thanks.....

A configuration along similar lines is available at the URL:

Simply put your PIX in place of the client shown. All clients behind the PIX could be translated by the PIX and then translated again by the 760. I haven't come accross such an implementation personally. You need to be sure of the security implications.
