yes i am using the Transmission plugin. I use your guid to setup sabnzbd,couch,transmission,nginx. After i confirm that all that is working then i start the openvn install which i use this guide. https://forums.freebsd.org/threads/54531/. Once that is completed and confirmed working i then implement a killswitch py script with the code below 
which i then use the freenas gui cron to run every 5 min. (jexec transmission_1 python2.7 /sabnzbd/scripts/pia.py
this checks VPN and create ipfw_rules so the internet works when openvpn works. I confirm this is working then i move to the last step which was the the port forward rule for pia and transmission script and then the errors come up.
Thank you for you time.
