However, I= have encountered an issue on the Container Network Interface (CNI) side an= d in order for it to work, the parameter /proc/sys/net/netfilter/nf_conntra= ck_max must be raised. You know that the container settings are managed by the hypervisor. However= , something prevents to go above 262144. By searching a bit in your code, I= found the limitation in Firewall.pm. I raised this value and the CNI works= again. The last change was in this commit that you made. https://lists.proxmox.com/pipermail/pve-devel/2019-October/039748.html Is it possible to take into consideration the increase of this parameter in= your code? Waiting for your feedback. Sincerely. Julien BLAIS
