Mainly you need to route incoming connections for the protocol in your modem if running at home, and ideally have dynamic DNS so your home IP address can have a name so other nodes can find its IP address as typically your provider will change your IP address from time to time...
Thanks for the info, MarkM. Will report back once I'm done setting the node up.
If you need a bigger amount of HZ (above 1000000 HZ), pm me... I have some.
Tried to send you a PM, ifinta, but newbies are not allowed to. If you can send me your price per HZ, I'd appreciate it.
