Troublesome PIX Config issue - Server cant access internet

Below is a config that appears almost line per line similar to a working config (I removed SNMP, Telnet etc..). The first PIX runs just perfectly.

The second which was being setting up this week has a few issues. First and foremost is the server at 192.168.111.2 (mapped to 55.xx.xx.202) has no outgoing or incoming traffic. I can ping the PIX and vice versa, but can not access anything on the internet. Now all other devices could pull up remote sites without issue via http.

The second issue, which may be related is just as troublesome. To test out whether I could access the webserver from the outside, I connected to a remote office via VNC web/java interface. Problem was once the java app began to load it would just hang. Several times I swapped out the PIX and used the old firewall and could connect to remote devices without issue. It seemed the PIX just did not like allowing such connections. Although at the office I have no problems with the first PIX accessing remote sites.

Now on the first PIX that we have had running for a long time, none of these issues exist.

Also I should add. In the internal network I have another webserver at 192.168.111.3. In a previous config I had that mapped to external 55.xx.xx.205 with an access to HTTP. From the outside there was no issue connecting to this webserver.

Lastly, this troublesome server at 192.168.111.2, well when I changed the IP address to 192.168.111.5 I had no trouble with connecting out to the internet. What in the PIX could specifically block a said IP address? The only listing was for the static mapping.

Any help or ideas will be greatly appriciated!

Here is the basic config, although the config has changed since I last worked on the device, having just erased the entire config, overall this is pretty much the same as before

One question,

Can you really use the 207 static? With your outside mask that ip shouldnt be avaible,.

Could you post the entire config!?
 
No we can't use the 207, I just caught that after, not thinking when I put in the 29 subnet. But for some reason, the ISP says we have IPs 201-207. Once that was taken out it fixed some of the problems. I say some, but not all

It wasn't until I swapped the outside address of 204 and made that 202, then the webserver at 202 to be 204 that everything started to work as planned.
