Ok, next question. I am total new so please bear with my stupid questions...
I have now different servers for each node.

Can I use 1 VPS for more than 1 masternode? I bough more ram and cpu to have enough, but I dont know if I can setup more than 1 node on each vps?
anyone have an good answer? any short advise or setup info to help? can I just add i on my config file?
