Thx for the answer.
I have been going through networking as an hobby since half a year with opnsense, vlan, routing stuff , docker & VMs.
I haven’t touched about VPN & public IP yet too much.
I will try to make all my current network RFC 1918 compliant tomorrrow & will try again with plex.
To share the importance of RFC-1918 for our servers.
The numbers you have conflict with Amazon’s servers.
RFC-1918 addresses are a subset of the total address block where all equipment knows to separate into LAN & WAN sides. This is the foundation for our LAN addresses. RFC-1918 addresses are not routable through the internet.
I can tell you my server is at 192.168.0.20 and it’s perfectly safe because the general internet will forward that address outside your own modem/router.
