can you post your nat and global commands that you have configured please. is the dynamic nat pool in the same network range as the IP address of your outside interface of the ASA?

with this configuration, what is the output of "show xlate".

also, have you tried something like:

global (outside) 1 x.x.x.15-x.x.x.28

global (outside) 1 x.x.x.29
