similar to: how to implement rate-limiting measures on interfaces using IPTables?

I have two VMs, both with firewalld installed. One on machine It this in the IN_public chain: Chain IN_public (2 references) pkts bytes target prot opt in out source destination 81 3423 IN_public_log all -- * * 0.0.0.0/0 0.0.0.0/0 81 3423 IN_public_deny all -- * * 0.0.0.0/0 0.0.0.0/0

Hi I would like to add rules into the iptables of the Hosted Engine VM in Ovirt. the version is oVirt Engine Version: 4.1.1.8-1.el7.centos I have tried using the normal process for iptables (iptables-save etc), but it seems that the file /etc/sysconfig/iptables this is ignored in the Ovirt Engine VM. How can I add permanent rules into the Engine VM? Kind regards Andrew

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'm running Centos 7.8.2003, with firewalld. I was getting huge numbers of ssh attempts per day from a few specific ip blocks. The offenders are 45.0.0.0/24, 49.0.0.0/24, 51.0.0.0/24, 111.0.0.0/24 and 118.0.0.0/24, and they amounted to a multiple thousands of attempts per day. I installed and configured fail2ban, but still saw a lot of attempts in the logs, and the ipset created was

Right? OK.

I apologize if this has been asked and answered, but I googled and attempted things for several hours today without success. I have a freshly installed CentOS 7 system that I'd like to disable the firewall and all iptables rules. Basically the equivalent of doing iptables -F In a nutshell I've tried the following commands, in many different ways and orders, but when the system

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 realize that firewalld uses iptables, but should it be enabled and started as a service? Jon -- Jon H. LaBadie jcu at labadie.us 11226 South Shore Rd. (703) 787-0688 (H)

Despite that the migration of our applications comes with a significant workload. It seems that also every aspect of common services had changed with EL8. In EL8 firewalld uses nftables as backend. I wonder why iptables does not list any rules while also configured to use nftables as backend. # iptables -V iptables v1.8.2 (nf_tables) # firewall-cmd --list-all |egrep -o '22|ssh' ssh
