Does anyone know if, since 10/31 update, has Minecraft changed the way it handles NAT?  Even after today's update I'm still unable to connect my server.  I'm running the minecraft client on the same machine that's hosting the server.

Prior to today I was receiving the "Took too long to connect, failed to login" error.  After today's update I now receive:

"Connection lost
Internal client error: java.net.ConnectExcpetion: Connection timed out: connect"

All of the information I've found on this issue so far pertains to Macs and talks about troubleshooting aspects of my server that have never changed.  Anyone outside of my server's local network can connect without a problem.  I can connect fine if I set online-mode=false, but this was only necessary AFTER the 10/31 update.

Does anyone with experience with the Minecraft networking codebase have any idea what could have changed?

Minecraft doesn't do any sort of NAT. That's handled by your router or firewall. Try connecting to the local IP of the server, rather than your external IP, if you're on the same network as the server.
