Ubuntu Networking :: Make 127.0.0.1:3306 Redirect To A Remote Mysql Server?

I'd love a hint or two on the following problem. I've set up iptables rules to forward all connections to port 3306 to a non-standard mysql port on a remote server. This works, except that I need to deal with the loopback interface in a special way and I'm stuck.

Code:
iptables -t nat -A PREROUTING -p tcp --dport 3306 -j DNAT --to 128.XXX.XXX.XXX:3197
iptables -A FORWARD -p tcp -d 128.XXX.XXX.XXX --dport 3197 -j ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE
Since locally-generated packets will never hit the PREROUTING rule, you'll need to setup a near identical rule using OUTPUT to make it work. Here is what I've tried:
