# Example cluster-wide firewall rules for /etc/pve/firewall/cluster.fw
|
|
#
|
|
# Stage 1 (single host, current): only the mgmt IPSET applies. Applied
|
|
# automatically by scripts/deploy-firewall.sh, which fills in <MGMT_CIDR>.
|
|
#
|
|
# Stage 2 (future cluster/Ceph): the corosync and Ceph rules below are
|
|
# commented out placeholders. Uncomment and fill in <COROSYNC_CIDR> /
|
|
# <CEPH_CIDR> when nodes 2/3 join and those networks actually exist -
|
|
# leaving them active on a single node with no corosync/Ceph traffic is
|
|
# just dead config, and a literal `<COROSYNC_CIDR>` is invalid syntax if
|
|
# left uncommented and unfilled.
|
|
#
|
|
# Copy to /etc/pve/firewall/cluster.fw and edit before enabling (or use
|
|
# scripts/deploy-firewall.sh).
