System Frezze with Firewall on.

Jan 12, 2023
Hello Community,

Since I started using the internal firewall in Proxmox, the host has been freezing irregularly.
The VMs and the host become unreachable. When I access my server via the KVM console, I usually see what is attached (kvm.png). After that, I restart the server, and it works again.

I had previously changed nf_conntrack_max and nf_conntrack_tcp_timeout_established because I found a similar case in the forum, but unfortunately, this did not help. (The current firewall settings are attached).

The system log is also attached.
If you need anything specific or have ideas on what I can try, please let me know.
I am currently using version 8.1.3.
