Hello,
Sorry to raise dust from such an old thread.. Found it via google, so thought to expand the same question a bit: can we ignore the Firewall enabled = yes in the proxmox hosts configuration of the firewall, e.g. Datacenter/ClusterNode1/Firewall/Options and Datacenter/ClusterNode2/Firewall/Options ? Now Datacenter is OFF, but hosts have it ON...
Purpise is to have the firewall OFF because I am setting up Shorewall on cluster node 1 which is the gateway.
