Ah.
If you're running the server on your PC and playing on it as well, then make your IP field in MySQL accounts to 127.0.0.1 and leave her's at 192.168.1.151. That might help a bit.
Set up the Minilogin server as if you were the only one connecting to it (make everything 127.0.0.1). The router should take care of the rest since your wife is playing on a separate PC on your LAN. Just put 127.0.0.1 in your eqhost.txt file (since you're connecting to the PC you have the server on), and make sure your wife's eqhost.txt says 192.168.1.150 since she's connecting to your PC. The router should forward all connections to your PC automatically.
If all else fails, you can use Hamachi. All that software does is create a VPN with unique ip addresses. There was talk about it a while ago on the forums. I've tried it myself once, and it worked fine. But try using it as a last result. I personally found it a thousand times easier to run a Public server and just lock it out to everyone except my friends and I. It's not eating bandwidth, either, since it's only connecting to the server to show my name on the list. All of the bandwidth is just the same as Minilogin. But better in terms of security.
If you need help with that, don't hesitate to ask.
