I've been working on this problem for about 2 days now and I have no idea what I'm doing anymore...I have a pix firewall that I'm playing with and I cant seem to get the setup right.

I tested out connection from the outside in using static with different ports and it seems to resolve fine. I can get to these servers and get out from INSIDE to OUTSIDE, however I cannot talk to my DMZ computer from the INSIDE and cannot talk from DMZ to the OUTSIDE.

I thought secuirty levels by default allowed all traffic to a lower security interface...but i cant get this going.

Any help would be appreciated.

Here is my running config:

pixfirewall(config)# sh run
