Convert emphasis to a heading.
Emphasis should not be used as a heading. Convert it to a proper heading.

Fix grammatical error.
The phrase "you can just additional iptables commands" is missing a verb. It should be "you can just add additional iptables commands".

Correct redundancy in the phrase "LAN network".
The phrase "LAN network" is redundant since "LAN" stands for "Local Area Network". Use "LAN" instead.

Proposed Changes
I had an issue about accessing every device in my LAN network, and as I wanted to shrink the possible attack surface, and cut off the possibility of accessing for example the router. The Wireguard is really secure, although there is a possibility of your WG client config file to be stolen, and thus I feel safer with single WG client config with control what devices I can access from external network.
I have spent a lot of time to find desired solution, and I would like to share it with the others, so you could be safer with your HomeAssistant :)
