I recently deleted one of my nat statements because i needed to change the address the inside was being natted to. well i removed the old and added a new. i see it in the running config. but when i ping from the outside world, the old address still answers and the new one does not. what could i be missing? i had to do this while the internal server was still up and running, could it be holding on to that public ip until i reboot both the pix and the server?
