...at proton.me (apologies if picking the wrong component) This happens on a Debian 12 system with custom kernel. On a arm64 router. On a fresh install, simply doing "firewall-cmd --add-interface=eth1 --zone=internal" causes a nftables error. The strange part, is that this only happens on firewalld's zones "internal" and "home". Actually i have tried other zones, but then, NAT does not work properly, even tough i have set the right rules and policies in firewalld. ######################################### root at banana1 /root $ firewall-cmd --add-interface=eth1 --zo...

I tried the following firewall-cmd --add-service=dns --permanent firewall-cmd --add-service=samba --permanent firewall-cmd --reload But was not able to connect until I disabled the iptables via iptables -P INPUT ACCEPT iptables -F then I was able to connect my windows 10 pro to my domain. So my question is what services or ports am I missing to open?

Hey all, I'm having a little trouble opening up a port on a C7 machine. Here's the default zone: [root at appd:~] #firewall-cmd --get-default-zone home So I try to add the port: [root at appd:~] #firewall-cmd --zone=home --add-port=8181/tcp success Then I reload firewalld: [root at appd:~] #firewall-cmd --reload success Simple! That should do it. Right? Well not quite. Cuz when I telnet to that host on that port, it's not connecting: #telnet appd.mydomain.com 8181 Trying xx.xx.xx.xx... <---obscuring the real IP telnet: connect to address xx.xx.xx.xx: Conn...

Is there any way to order rich rules in firewalld? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like. Alternatively, how can I change the default policy of a firewalld zone? At the moment I don't see any way to have a zone accept traffic by default other than adding a rich rule allowi...

After a recent large update, firewalld's status contains many lines of the form: WARNING: COMMAND_FAILED: '/usr/sbin/iptables... Checking iptables.service status shows it to be masked.

I don't really understand the intent behind firewalld. The RHEL7 Security Guide states "A graphical configuration tool, *firewall-config*, is used to configure firewalld, which in turn uses *iptables tool* to communicate with *Netfilter* in the kernel which implements packet filtering". So is the goal for firewalld to implement a GUI for ip...

I just noticed that when rebooting a CentOS 7 server the firewall comes back up with both interfaces set to REJECT, instead of the eth1 interface set to ACCEPT as defined in 'permanent' firewalld configuration files. All servers are up to date. By "just noticed" I mean that I finally investigated why a newly rebooted VM failed to allow NFS connections. Prior to doing that. I'd been stopping the firewall to get access, then restarting the firewall after setting the eth1 inte...

Is there an Apache tool to manage firewalld on a headless server? I am looking forward to my next Centos project which is to replace my Juniper SSG5 firewall... And along that line, what overlap, if any between firewalld and Suricata? thank you

Yesterday I noticed that I was not able to ping one of our development servers so I logged in via VNC and ran the Firewalld GUI. To my surprise, except for the interface definition for public and trusted zones, nothing seemed to be configured. That is, none of the services were checked off that we want open at the firewall. Also, this server is a gateway and masquerading and forwarding appears to be off as well. So...
