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

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)

Hi all! I'n wondering if it is possible to have Centos-7 automatically change firewall zones, depending on the network we conect to. my default zone is "home" and it has some ports open that probably shouldn't be open when I'm on someone elose's network. so I'm thinking that if there's a way to have it always use home when I'm at home, and external when

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

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

Well, there are about 20 of

On CentOS 7 with firewalld I have a box with numerous interfaces acting as a NAT gateway. This works but I noticed that it routes/forwards traffic not just from my internal zone to external zone but also between interfaces within the internal zone. How can I prevent that traffic? I've tried adding direct and rich rules to deny the traffic but it doesn't work. Direct: firewall-cmd

You should think about using alternate repositories like from launchpad. The most common repository used seems the one from sernet. You need to register at sernet for this.
