I have problem with claster on proxmox 6.
My claster config /etc/pve/corosync.conf
logging {
  debug: off
  to_syslog: yes

nodelist {
  node {
    name: pv1
    nodeid: 2
    quorum_votes: 1
  node {
    name: pv2
    nodeid: 1
    quorum_votes: 1

quorum {
  provider: corosync_votequorum

totem {
  cluster_name: cl1
  config_version: 2
  interface {
    linknumber: 0
  ip_version: ipv4-6
  secauth: on
  version: 2
In /etc/hosts I have: pv1 pv2

So replication vm should be made by NIC associateed to ip and, but isnot, tpcdump shows that there is traffic beetwen nics connected to ISP on public ip.
How can i force proxmox to use lan nic for replication ?
you can add the following line:
migration: <secure|insecure>, network=<CIDR>
to '/etc/pve/datacenter.cfg'. See here for the specifics. Then PVE will use that network for migration and replication. But it is not recommended to use the cluster network for this, since corosync requires low latency.
