You must ensure that no rule exists in iptables or firewalld that will prevent PTP packets from reaching the slave sfptpd process.

  • The following command is a useful starting point to examine iptables rules:
    # iptables -L

    The iptables service can be temporarily disabled to identify if it is responsible for blocking PTP traffic:

    # service iptables stop
  • Firewalld can be temporarily disabled to identify if it is responsible for blocking PTP traffic:
    # systemctl stop firewalld
