First time arch installer.

Two strange things happened since a successful installation about a week ago:

I had been playing World of Warcraft for 3 days with firewalld blocking all ICMP permanently.

Than all of a sudden, I could not login to play Wow

So I disabled the firewalld and switched back to using the UFW/GUFW..!

I have a gnome "tweak" that starts the ufw program upon loggin in, and all I have to do is flick the switch on GUFW to "on" to REJECT ALL incoming traffic.

Well this morning I became fed up with it, so I added a UFW startup service using the systemctl command:

Upon rebooting, I was greeted with a black screen of death!

I obtained a command line by pressing CTRL + ALT + F2 i think, and was able to re-gain root privilege to disable the systemctl startup service for my UFW.

After that the problem was fixed.

I just thought it seemed strange.

The only UFW firewall rule I have is for limit the SSH connections for Port #22, and the only other changes I made to the UFW program were to REJECT ICMP type echo requests to my PC.

On a side note, using sshguard with ufw will not allow me to login to the World of Warcraft either.

I really hope this helps someone!

No, your display server or desktop manager doesn't start - it probably wants to phone home?
Check the system journal for the previous boot, you'll likely find GDM or SDDM or so complaining about something and then failing to start.

Also inspect the actual UFW configuration, iptables/nftables, because I'm not sure how to square these two statements:

flick the switch on GUFW to "on" to REJECT ALL incoming traffic.

thank you. i kind of mish mashed two different issues here, but for me they are one and the same: getting world of warcraft to stop hacking my pc - i swear to god "blizzard" (microsoft) is the front lines of every investigative database in america, and more - and after hours of removing and resetting everything in multiple ways and starting over from scratch, the only way to get the world of warcraft up and running for me was to manually add the game in ufw using the + symbol to add a "preconfigured" rule, now i'm going to start all over again, step by step, to test what and will not work and what does not. it seems they have a few days window of leeway to confuse the hell out of anyone trying to play wow with ufw, which had nothing to do with this post i admit. except everything imo. lol!
