Gufx firewall sufficiency
 

Hello!
I'm pretty new to the world of Linux. Right now I use Ubuntu Desktop 14.04 Later down the road I plan to install LAMP to try to run a web server.
Generally speaking, I prefer GUI (as most people, I guess), though I have no problem with CLI (remember myself in 1990 with MS-DOS).
As a regular user I don't think I really need a firewall in Ubuntu. Sticking to installation defaults is fine by me. But as an admin of a web server, I would think that I'm gonna need something beyond the Desktop ed. defaults security-wise. I'm aware of IPtables, of course. But to me it seems a little bit too much to learn, too steep of a learning curve right now. Then there's ufw.
And a GUI front-end of it, which is Gufw. Here opinions vary. Some say, I must learn IPtables, others think that Gufw does its job fine.
So what I'm asking here is not just an OPINION, but also a reasoning behind it. Real life example maybe etc.
Thank you.

gufw is just a frontend for configuring iptables. iptables still manages the firewall.

Run gufw and configure iptables. You won't have to run gufw (or ufw or an equivalent) again unless you want to change your firewall configuration.

You can check your firewall configuration by running

from the command line. Depending on your distro, you may have to run it as root.

I think it would be worthwhile to manage your own firewall.

Thanks for your reply!
Yes, I would do that.
