What to use to manage a router and firewall on RHEL 9?

I have been using FWbuilder which was a nice Windows package to make and manage network firewalls and routing rules on a Centos 6 system

It all has to go as FW builder was discontinued years ago and doesn’t handle firewalld and Centos 6 - enuff said!

I don’t run a GUI on any of my Linux boxes, but I like the idea of managing etc from my Windows desktop.

Open to all suggestions, but would rather use RHEL for the router and not eg a Cisco.

Other than the built in functions? This is kinda the purpose of Webmin. I guess the downside is it isn’t as ‘braindead’ an interface as what you would expect in a GUI. More of a ‘helps you manage’ what’s already there.

Some use this for the firewall which I think is what you might be after. I think one of the site admins uses it.

As a former CCNP, I don’t know any comparable routing interfaces for Linux.


Is this for your home network? I use pfsense installed on an old dell computer with a 5 port gig extension card.


Webmin is for a simple firewall for “this server”. It can display rich rules, but as far as I can see it can’t create them.

Configserver is also just for “this server” from a quick read.

I will have a look at pfsense - thanks.

OPNsense is a fork from developers of PFsense but has more features for free.
Both appliances are a little intense to get setup and configured but offer amazing protection and adaptability for inbound or outbound networking.
