Cisco PIX 506E
I'd like to use my Cisco PIX as the default gateway of my network and the access point to the Internet.
However, I can't seem to get it work. I'm not able to ping the Internet nor am I able to browse.
Can someone provide a detailed explanation of what I need to do?
--------------------------
Here is the architecture.
Cisco PIX Inside IP: 192.168.1.2
Cisco PIX Outside IP: 66.66.66.66 (masked)
Local Machine IP Address: 192.168.1.100
--------------------------
Here is the local machine configuration.
IP Address: 192.168.1.100
Mask: 255.255.255.0
Default Gateway: 192.168.1.2
DNS 1: 192.168.1.2
DNS 2: 217.217.217.217 (masked)
--------------------------
Here is my PIX configuration.

lrmoore,
Once again, you have come to my rescue.
I entered the lines you recommended:
no nat (inside) 0 0.0.0.0 0.0.0.0 0 0
global (outside) 10 interface
nat (inside) 10 192.168.1.0 255.255.255.0
And then... I had to add 2 rules to my access list.
access-list inside_access_in permit udp 192.168.1.0 255.255.255.0 host dns_server eq domain
access-list inside_access_in permit tcp 192.168.1.0 255.255.255.0 any eq www
Thank you so much for all your assistance!

The problem is that you are trying to use the PIX as your DNS. Don't. The PIX will not proxy dns for you.
Make sure that DNS 2: 217.217.217.217 becomes DNS1
Don't worry that you can't ping anything. You would have to create an access-list to allow the ping replies back in.
You also need a global and a nat statement:
no nat (inside) 0 0.0.0.0 0.0.0.0 0 0
global (outside) 10 interface
nat (inside) 10 192.168.1.0 255.255.255.0
