After IOS upgrade, can't get globals/nats right.

Odd thing is, the original global/nat setup will not work with the new IOS. I am 99% sure it has nothing to do with the Access lists, but I can post them if needed.

Problem: With the new config, in the "library" which uses 192.168.11.0, if they check their outside ip from WHATISMYIP.COM or similar service, it shows up as 198.31.145.10. In order for the DB application to work, their IP MUST show up as 198.31.145.11 After an IOS upgrade and conduit conversion, the "original" config no longer allowed ANY internet access from the 10 range. After the changes, I was able to access the internet, but nothing else worked correctly (library had wrong outside ip).
The DMZ can be ignored for the time being.

Original:

ip address outside 198.31.145.10 255.255.255.0
global (outside) 1 198.31.145.11 netmask 255.255.255.255
global (dmz) 1 192.168.31.230
nat (inside) 0 access-list 108
nat (inside) 1 192.168.11.0 255.255.255.0 0 0 ("Library")
nat (inside) 1 192.168.40.0 255.255.255.0 0 0
nat (inside) 1 10.0.0.0 255.0.0.0 0 0 (All our client PC's are in the 10 range)
nat (dmz) 1 192.168.30.0 255.255.255.0 0 0
------------------------------------------------------------------------
Cisco person changed to:

ip address outside 198.31.145.10 255.255.255.0
global (outside) 2 198.31.145.11 netmask 255.255.255.255
global (outside) 3 interface
nat (inside) 2 192.168.11.0 255.255.255.0 0 0 ("Library")
nat (inside) 1 192.168.40.0 255.255.255.0 0 0
nat (inside) 3 0.0.0.0 0.0.0.0 0 0 (All our client PC's are in the 10 range)
nat (dmz) 1 192.168.31.0 255.255.255.0 0 0
------------------------------------------------------------------------

Hi narcus,
You shouldn't specify the netmask in the 'global' command. I suspect it is being ignored so the second command is being used which is the interface of the PIX. Paste the following into the configuration :-

no global (outside) 2 198.31.145.11 netmask 255.255.255.255
no global (outside) 3 interface
global (outside) 1 198.31.145.11
