21117 port should be open. Check if they are open or not on http://Yougetsignal.com/tools/open-ports/ if they are not open then you can use this software http://download.cnet.com/SPI-Port-Forward/3000-2651_4-10764348.html on VPS to open the ports. Remote Ip in this software will be your Internet IP
so now im worried that my masternode wont work. i did the test with yougetsignal and port 21117 is closd. i downloaded the sofrware to open ports but dont understand the values ii need to enter.
can anyone help?
