Hello everyone! I've been thinking about opening a server on my computer using a DNS. The question i had is: can people hack my and my parents their computer trough me opening a port (with firewall) for a minecraft server. People connect to my server using a DNS. witch is hosted at http://www.dtdns.com Is it safe to do this? It might seem silly I think its safe. But my dad wants to be sure to give me his password for me to open the port. Anyone? P.S. I've already tryed google. But I only found people posting about players that just want to scare people. I know theese.
