Networking noob here. I want to prevent all incoming requests except through a specific port, and that traffic is forwarded to a specific device on the network. NAT seems to do that just fine, it’s almost like a kind of firewall by itself. What kind of threats are there that requires more than just NAT for security?
IPv6 usually have unique IP addresses (non-local) for every device in the network. does that mean it will malicious actors can target a device specifically inside a network?
I haven’t setup an IPv6 network yet, but it’d have to physically traverse the packet through your router to reach the connected device still. I imagine a router would still be able to use it’s firewall to drop the packet before it gets sent to the endpoint device.
