firewall - NAT translation with Cisco ASA 5505

I am trying to setup NAT translation on a ASA 5505, however the new public IP address never actually becomes available after adding it. I'm sure I'm doing something stupid, but so far the problem has eluded me. Basically, I'm trying to map XX.XX.115.195 => 192.168.125.7. XX.XX.115.194 is the public IP of the firewall, and it is accessible, but 115.195 never seems to get picked up. I inherited the original configuration so it is possible that one of the other rules is preventing this from happening. I've included what I believe are the relevant sections below.

Below is the specific rule I added. I've confirmed I'm able to reach the 125.7 server from inside the firewall on the usual ports and protocols, but from the outside the public 115.195 does not respond to anything.

static (outside,inside) 192.168.125.7 XX.XX.115.195 netmask 255.255.255.255
