Disabling default Proxmox firewall

by Jan Bachelor

  • In order to remove interference between the Proxmox firewall and OPNSense, it is highly advisable to disable firewall on the Proxmox instance and on all VMs / containers. 
  • To disable Proxmox firewall functionality on the node itself, go to Datacenter -> ‘Proxmox’ node -> Firewall -> Options and for the item called ‘Firewall’, set it to ‘No’.

Disable Proxmox’s firewall that will be replaced by OPNSense

Go back to course overview: Build Your Own Router – Proxmox, OPNSense, OpenVPN server and a VPN client all in one!
