Hi,
When I try to enable built-in firewall, everything seems to be working, but then are randomly some connections to proxmox node dropped. (VM seems unaffected, but they do not have "centralized" firewall enabled)
It does not depends on the number of firewall rules or mode (default DROP or default ALLOW), basically it happens even with the simplest possible configuration (default ALLOW and 1 rule to DROP traffic).
I have inspected all logs in /var/log (dmesg included), found nothing.
/proc/sys/net/netfilter/nf_conntrack_count is very low (below 1000), /proc/sys/net/nf_conntrack_max = 65536.
I'm running latest Proxmox.
