@frmiqueias Did you managed to configure centos 7 vm network? cause i just installed a vm with centos 7 (in proxmox 7) and i am facing the same problem, i cant acess the network.

Any help with this kind of problem? I cant access my centos VM if i turn csf firewall on.

So basically no one is using csf firewall with centos in proxmox 7? Or centos web panel in proxmox 7? I already paid centos web panel support so they can solve the problem, but after some time searching for the solution they told me that the reason why csf is disabling the centos vm network is...

Nice help ;)

I think you need to disable the centos firewall mate (i did it in my VM so it works) ;) Commands to disable: systemctl stop firewalld systemctl disable firewalld

Forget about "hwaddress" (only needed in Proxmox 7). Install iptables: apt-get install -y iptables-persistent The iptable rules will be in: /etc/iptables/rules.v4 Then add the respective rules i sent to you (edit the rules with your ips). To apply them: service netfilter-persistent reload

Sure ;) auto lo iface lo inet loopback iface lo inet6 loopback auto ens3f0 iface ens3f0 inet manual auto vmbr0 iface vmbr0 inet static address 146.xx5.xx3.100/24 gateway 146.xx5.xx3.254 bridge-ports ens3f0 bridge-stp off bridge-fd 0 hwaddress...

I'm with Proxmox 7 and Centos 8 Stream VM Using the virtual mac address. Only needed to configure the server like this. Then you need to add your failover ip in your dedicated server iptables Command: nano /etc/iptables Private ip used in Centos VM = 192.168.1.52 Failover ip used in Centos...

No one knows why centos 8 stream csf firewall cancels the VM network connection when activated? Centos 8 Stream VM Proxmox 7

@fabian I think not, but i will test it and let you know ;)

Exactly mate ;) But if you install for example one lxc from this link, it will work. Test it, just so i can have your opinion: https://uk.images.linuxcontainers.org/images/ (at least i tested with the last Debian 10 version from that link and it worked with no problems!)

Currently my main problem is different. I cant activate csf firewall in a centos container or VM, cause i loose access to the network. Here: https://forum.proxmox.com/threads/centos-web-panel-csf-firewall-problems.93884/#post-408491

1. I do not have an OVH vps, i have an OVH dedicated server. 2. I do not have problems with FailOver ips, only with the default server ip 3. My network is NATed too This problem is "solved" if i use a recent Debian container version (10.10). Link...

Do not go to v7, it is still not stable. There are a few bugs, so it is better to use v6.4-13 ;)

No, thats impossible.. I already told that this problem only ocurs when using the default dedicated server ip. With failover ips it works like a charm. Anyway, it works with another Debian template i tested. Seems to be one more bug coming with Proxmox 7 ;) I'm really thinking about going back...

Hi I installed centos web panel in a vm and in a container with centos 7 and centos 8 (Proxmox 7). (i've tested both systems) The thing is, when i enable csf firewall in centos web panel i completely loose access to the panel (even with my ip added to the whitelist rules). I contacted Centos...

I just tested with another debian lxc version / option and it seems to work with no problems Link: https://uk.images.linuxcontainers.org/images/debian/buster/amd64/default/20210803_05:24/rootfs.tar.xz

Thats only a file i created to automatically restart ssh everytime the container starts (just to try to solve the problem). But you can ignore that file, is not being executed, it was only a test that i tried to run (i removed it from cron).
