Hey guys,
Another update. So I do need a managed switch but I am going to have to wait for my tax return (minimum 16 port switch though). I now have 5 internal clients and 3 external for plex and it is running great still. I had upgraded my internet connection too since rogers has changed there policies a bit so I qualify now. I also figured out the minecraft server and ownCloud. My freeNAS system is handling it all extremely well. It sucks that I can't get over 80mb/s write or 70mb/s read but everything works otherwise. I believe this to be related to the configuration of drives (raidZ2 + SSD cache).
Very happy I got plex working, it is an amazing setup. Got lifetime membership.
Kind Regards,
Wally
