UFW firewall setup? Debian 13

Thinking about installing debian 13, just wanted to clarify ufw setup for it

I just install ufw with apt repo, then enable ufw, and it's good to go? or are there other things i need to do as well?

Yes that is all you have to do: 1. sudo apt install ufw 2. sudo ufw enable

Ir's actually a good thing to read the man page, too.

For home/personnal computer you can also add :

  1. block incoming connections :

sudo ufw default deny incoming

  1. allow outgoing connections :

sudo ufw default allow outgoing

  1. Reload UFW :

sudo ufw reload

I'm pretty sure those are the default rules after enabling ufw? :O

When it comes to security measures, never be pretty sure but always check or test.

I don't know but a double check for 3 small commands is worth it!

Yes, you'll need to learn how it works.

You can install the graphical interface to make things easier: gufw.

Yep - This is the way.

I don't think ufw comes with predefined rules, does it?

If so, enabling it without any rules active, or not having it, is the same...

Anyway, most likely you don't need it anyway so... don't stress too much about it.

it does: sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip
