I am my PC as server with DSL Dynamic IP, so I use No-IP to get my static address but for a while i use dynamic ip to test.

I was setting my modem to forwarding mysql port (3306) and ssh port(22), and status OPEN checked from http://www.yougetsignal.com/tools/open-ports/

But when i tried to connect it appear error

PLINK : Fatal Error : Network Error : Connection refused and then next error (attached)
