Transparent mode setup

Unanswered Question
May 23rd, 2007

I am in the process of setting up a PIX 515e box in transparent mode. I have done all the basic configurations (set my inside and outside interfaces/enabled them, set the management interface, etc). I can ping from the device to both inside and outside hosts and I can manage the device from either inside or outside. My problem is that I cannot communicate between inside and outside hosts. The PIX does not seem to be passing traffic.

Am I missing someing in the basic configuration ?

Version is 7.2(2)

Thanks for any help!

I have this problem too.

I went through that as part of my troubleshooting, in fact I used the info from that training module to configure the pix box. Am I wrong in assuming that the basic config as outlined in the training module should get the box up and running and passing traffic from inside to outside hosts?

Here is the config, I've blocked out IPs and the hostname, it should be a default config except for the admin accesses that have been set up.
