Security issues with port fowarding

Question

If I was to forward a port (for Minecraft server) would it pose any security issues at all?

I have X amount of devices connected to my one network, and I’d not like them to be “hacked”.

I know I can use Amazon or a VPS for running the server, which would be ulta-safe, but it’s too expensive.

Answer

Only in the sense that if someone could exploit your Minecraft server, they’ve now got control over a server inside your network, ‘behind’ your firewall.

Other than that, there’s little risk.

edit I should have said ‘behind the firewall’, rather than ‘behind the nat’.
