I'm installing a PIX 501 in an environment where the T-1 first passes through a router over which I have no control, then to my PIX, and on to the clients. (I can't place the PIX any further upstream than this).
The documentation says to install a crossover cable between the internet (or the router in my case) and the PIX, and straight-through cables everywhere else.
When I do this, nothing works. However, when I use a straight-through cable from the router to the PIX, and a crossover from the PIX to a client, it works.
I can't imagine the docs are wrong (someone would have noticed by now).
Why does my configuration not work as depicted?
Do I need to get crossover cables for all clients behind the PIX? (Tell me no, please).
Thanks for the help.
