I want to setup port forwarding for a Minecraft server I have so that others can access it ,but I’m not sure how safe it is. Can anyone shed some light on this?
In: Technology
Port forwarding would not be needed at all if the single and properly configured computer were directly connected to the modem, rather than with the middleman of a router.
The function of the router is to give you a single IP address – four numbers in form xxx.xxx.xxx.xxx – and let that single address serve internet to multiple computers rather than just one. (If you look, your modem will have only one Ethernet network connector, and your router probably several.)
The router doesn’t really do active server sorts of things itself, though, so if there is more than one computer, that HTTP request through the router must have answered: requesting from which machine, exactly?
Your computer probably has Windows Firewall already going, to keep the actual safeties in check by questioning you whenever any of your programs asks to communicate on the Internet. The router’s firewall, into which is put the permissions of port forwarding, is less for security and more to answer: to which machine?
