For some reason, phrel unsuccessful message stopped showing in my message log almost 20 hours ago. Realized that iptables path was wrong in the config file, so proceed to correct that and fired a couple of phrel commands again.
Now what happens is that ONLY ip6tables errors appear, eventhough deactivated IPV6 in the conf file: command not successful: /sbin/ip6tables -L phreld-sync-check-5ce2 > /dev/null 2>&1
Yes, I'm running as root too. BTW, /sbin/iptabless -L does not show any reference to phrel.
