Built in firewall ...

[kingdragonbg]

I know I could install one but I’d rather not go through that hassle that I keep reading about ... think it be best if valve added a built in firewall for extra protection and yes I know Linux has its own ports all closed off and router has a firewall and such but if you think about it I rather there be no chance / risk at all and they add the firewall built in so we can be even more protected and security is first after all so valve or kde need to do this it be so much better

I thought KDE Plasma already had a GUI for a software firewall; Basically a front-end for ufw and firewalld.

Firewalld does not appear to be installed on the Steam Deck.

There is no need for an outgoing firewall if you trust the software on the device.
There is no need for an incoming firewall if nothing is listening on the interface to begin with.

That said, there are definitely some ports listening that would probably be a good idea for them to let you close when connected to public WiFi.

but the firewall isnt pre built you need to install and set it up ... it be better if they had an enable firewall button with a prbuilt in one for you it be helpful in public wifis and stuff maybe even built in vpn extra protection/ privacy since linux is all about that

Essential feature to have, with all inbound disabled, except things needed for IPv6 to properly function.
