Hi, If possible advice me for below error. [root at ns1 sysconfig]# iptables-restore < /etc/sysconfig/iptables iptables-restore: line 2 failed Thanks in advance.

Hi! I have a server running CentOS 7.7 (1908) with all current patches installed. I think this server should be a quite standard installation with no specialities On this server I have fail2ban with an apache and openvpn configuration. I'm using firewalld to manage the firewall rules. Fail2an is configured to use firewalld: [root at server ~]# ll /etc/fail2ban/jail.d/ insgesamt 12

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 iptables? What is the "value added"

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

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 am trying to build a new openvpn server based on CentOS7. Everything is working fine as long as I disable firewalld. With firewalld enabled, I can connect to the vpn and ping the machines on the network, but I am unable to ssh to them. What I had on my old server with iptables was two simple rules: -A RH-Firewall-1-INPUT -s <localnet>/255.255.0.0 -d <vpnnet>/255.255.0.0 -j
