Greetings, One of my biggest frustrations with CentOS 7 has been firewalld. Essentially all of the documentation just flat doesn't work. One common thing that needs to be done is to change the zone of an interface, however I've tried: firewall-cmd --permanent --zone=internal --change-interface=ens192 firewall-cmd --permanent --zone=internal --add-interface=ens192 I've also tried

Hi, In CentOS7 I have added two zones using firewall-cmd, each for different ports/services and interfaces when I try to --add-source to the second zone with an IP that is already in the first I am getting an 'Error: ZONE_CONFLICT' message. Am I trying to do something illogical or is this a feature? Cheers, Colin.

I have a number of machines (hardware and VMs) running CentOS 7. I all cases firewall-config is not functional. First, the service check boxes are not functional. When you click on one, it don't change to "checked", and nothing changes on the firewall. However you do see a "Changes applied" Sometimes, f you go to permanent mode and attempt to edit a zone, the whole

Dear Members, Please tell me how can I fix this problem. Against allow imap on firewalld, I cannot access to the server. [root at speedex ~]# telnet 153.153.xxx.xxx 110 Trying 153.153.xxx.xxx... telnet: connect to address 153.153.xxx.xxx: No route to host After stopping forewalld I can access to the server. [root at speedex ~]# telnet 153.153.xxx.xxx 110 Trying 153.153.xxx.xxx... Connected to

I'm still learning firewalld obviously, and I am having trouble groking the documentation to understand how to do this. I know I could do an iptables direct, but that doesn't seem like the "right" way to do it. What I'm trying to do is allow a specific service, only for a specific ip. Effectively, SNMP should be allowed form a specific IP address (the systems monitor).

How do I insert the iptables rule below using firewalld? I'm moving up from CentOS 6 to 7 on an office gateway and I'm trying to get OpenVPN working to allow home workers to access PCs at the office. I've got it all working but only by manually inserting an ACCEPT rule in the FORWARD iptables chain: iptables -I FORWARD 3 -i tun+ -j ACCEPT This rule was extracted from my iptables

You need to add pop3. Please note that op3 is not secure as password and username is transferred in plain text. *firewall-cmd --add-service=pop3 --permanent* *firewall-cmd --reload--* *Eero* 2016-07-14 11:43 GMT+03:00 Subscriber <ml-lists at agoris.net.ua>: > > Thursday, July 14, 2016, 11:32:31 AM, you wrote: > > > Dear Members, > > > Please tell me how

Hi, I just setup a very basic HTTP proxy with Squid on a router running CentOS 7. Up until early 2020 I've been using a bone-headed shell script with iptables to configure my firewall. But I decided to follow advice from a few gurus on this list, and I've since moved my configurations to FirewallD, which works nicely. There's one configuration left to tackle, that's port
