You didn't say what is the kernel version. If it is >=3D 2.6.11, you're s=
tuck.

As I suggested to someone else having the same problem as you, instead=20
of using a DNAT rule you may use a TCP "proxy" such as stone=20
(<http://www.gcd.org/sengoku/stone/>, supports UDP too) or 6tunnel=20
(<http://toxygen.net/6tunnel/>, originally designed to relay connections=20
between IPv6 and IPv4 hosts but works between IPv4 hosts too) which=20
listens on the local port 3306 and relays the local connexions to the=20
remote SQL server.
