<pre>sudo iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT</pre>

<pre>sudo iptables -A INPUT -i lo -p tcp --dport 5000 -j ACCEPT</pre>
<blockquote>Allow Home Assistant access to port 5000

<pre>sudo iptables -A INPUT -s 192.168.5.4 -p tcp --dport 5000 -j ACCEPT</pre>
<blockquote>Block all other access to port 5000
</blockquote>
<pre>sudo iptables -A INPUT -p tcp --dport 5000 -j DROP</pre>

</blockquote>
<pre>sudo iptables -I DOCKER-USER -j RETURN</pre>
<blockquote>Install the <code>iptables-persistent</code> package:
</blockquote>
<pre>sudo apt install iptables-persistent</pre>
# During installation, you’ll be asked if you want to save the current iptables rules. Choose Yes.
# If you’re not prompted, you can manually save the rules by running: <code>sudo netfilter-persistent save</code>
# YOU NEED TO INSTALL <code>IPTABLES-PERSISTENT</code> AND TELL IT TO SAVE YOUR RULES OR ELSE YOU HAVE TO RUN THIS EVERY TIME YOU BOOT!
