Webmin or a easy way to manage a firewall
 

I use webmin to manage my ubuntu headless server. So I was looking to try and find a webmin module that could help me secure my server with a firewall.

My normal rules are allow all access from my office and block everything else, with the exception of opening the ports for rtorrent

I like a gui so I can look at logs and tweak other things I was looking at CSF but I just was not sure how that linked in to IP tables or how that differed from just using iptables.

Any help on a recommended webmin or webbased firewall or help in setting up my rules would be great.

I see these Webmin modules that appear to address firewalls:
FirewallD
Linux Firewall
Linux IPv6 Firewall
Shoreline Firewall
Shorewall6 Firewall

Suggest using the Webmin search function...enter "firewall" (no quotes) there...

Thanks I started with CFS but it has a step learning curve, I like FirewallD and the idea of zones but would like to see some more documentation on the webmin module as most of it is just standard man stuff.

So FirewallD is installed and I want to manage it from webmin but I cant see how to add a ip address to a rule

Any one able to help or do I have to use the CLI

https://doxfer.webmin.com/Webmin/FirewallD ?

That is just a picture it does not print a 1000 words to me. I still cant see how to add a IP address to a zone from within "Webmin"

I'm not seeing how to do that with Webmin either, so I'm learning firewall-cmd.
Excerpt from a bash shell script I wrote so I didn't have to remember what to do to block 1 IP address
...where $IP is passed in from the command line. The first line make an immediate change; the second line makes it survive reboots.
which is onerous...I've done a lot of web searching, too.

I'm not finding a GUI or web interface yet. Nor have I looked at the other webmin modules, yet.

NOTE: I'm on CentOS 7 so ymmv

https://doxfer.webmin.com is Webmin's Documentation Portal.

Webmin_Modules >
I see several possible entries under modules...(these may not all be present/enabled on your install).
FirewallD
IPFilter_Firewall
Linux_Firewall

One of those has the solution. Maybe two modules are involved. Perhaps, perhaps not.
I don't know what you mean by "easy way to manage a firewall". Hire an Admin? Or Learn to be One.
English is what I got at Documentation Portal
You can select the Documentation Portal's language but that only accommodates the wiki-driven site
elements. The actual content seems to remain in English.
I apologize for the brevity here.

If you "I like a gui so I can look at logs and tweak other things" - then webmin is the place.
I liked looking at logs so much, that I built a solution. an "ELK stack"

Both tasks can be accomplished at a terminal prompt "easily". IMHO

"help", "easy"...
No hablo. Lo Siento.

Buenas Suerte.

You could try a firewall distro.
