Title: securing IoT devices

If you're self-hosting, it would be very
important to think about how you plan on
securing your device.

Types of firewalls:
Packet filtering: examines individual packets
and makes decisions based on source, destination,
IP, protocol, and port number
Stateful inspection: they maintain connection state 
information, they track the state of active connections
and make decisions based on the context of traffic flow.
Remembering previous connections and can determine
whether a packet is part of an established connection.
App layer firewalls/proxy firewalls: they examine the 
actual content of packets and understand application
protocols like http, ftp, and smtp.

Make sure you allow the minimum necessary access.
Start with deny-all, add only what is explicitly
required to be open to the internet.

I recommend isolating different IoT devices to
reduce risk of any infections spreading.
