Cisco PIX Default Config but No Outside Access from Inside

Apologies if this is so basic.

I'm not able to route from the inside interface to the outside after restting a 506e to default factory configuration and making a few minor customizations.  It never worked with the factory defaults and I've now exhausted my little knowledge of how to reconfigure this properly.

I set the outside interface with an address on my local (working) subnet 10.100.100.0 and plugged it into Interface0.  I've confirmed the outside interface of the PIX is indeed pingable from my active production subnet.

I set the inside interface to provide DHCP in the 172.18.16.x range and added things like DNS and WINS that exist on my production subnet.  I've confirmed when I plug my laptop into Interface1 it gets a valid IP address from the PIX in the correct range; also correct are the DNS and WINS addresses.  So DHCP works.  And I can ping the PIX inside address.

So both sides work, but they don't apparently talk to each other.  However, any attempt to access anything on my 10.100.100.0 subnet fails.  It just times out.

Another clue, perhaps unrelated:  On the laptop (connected to the inside interface) I can browse to https://172.18.16.1 and, in fact, get a website security certificate error.  I click on "Continue to this website" and get prompted for the User name and Password which I enter as blank (first time).  I get the PDM 3.0 spalsh screen and allow pop-ups always.  I go to the new "popped up" browser window and it says "Loading PIX Device Manager. Please wait ..."  That's as far as it ever gets.

This PIX was working perfectly on another production subnet before I reset it to its factory defaults.  So I suspect it's my lack of knowledge and not something inherently broken with the device.

I've copied the configuration below.

Thanks very much.
