Here are the steps to run it on a Synology NAS (Tested on DSM 6) :

• Connect as admin to your Synology SSH
• Switch to root with command sudo su -
• Enter your admin password when prompted
• Create a TUN.sh file anywhere in your synology file system by typing vim /volume1/foldername/TUN.sh replacing foldername with any folder you created on your Synology
• Paste @timkelty 's script :

#!/bin/sh

# Create the necessary file structure for /dev/net/tun
if ( [ ! -c /dev/net/tun ] ); then
	if ( [ ! -d /dev/net ] ); then
		mkdir -m 755 /dev/net
	fi
	mknod /dev/net/tun c 10 200
	chmod 0755 /dev/net/tun
fi

# Load the tun module if not already loaded
if ( !(lsmod | grep -q "^tun\s") ); then
	insmod /lib/modules/tun.ko
fi

• Save the file with [escape] + :wq!
• Go in the folder containing your script : cd /volume1/foldername/
• Check permission with chmod 0755 TUN.sh
• Run it with ./TUN.sh
• Return to initial directory typing cd
• Create the DNS config file by typing vim /volume1/foldername/resolv.conf
• Paste the following lines :

nameserver 8.8.8.8
nameserver 8.8.4.4

• Save the file with [escape] + :wq!

• Create your docker container with a the following command line:

  # Tested on DSM 6.1.4-15217 Update 1, Docker Package 17.05.0-0349
  docker run \
      --cap-add=NET_ADMIN \
      --device=/dev/net/tun \
      -d \
      -v /volume1/foldername/resolv.conf:/etc/resolv.conf \
      -v /volume1/yourpath/:/data \
      -e "OPENVPN_PROVIDER=PIA" \
      -e "OPENVPN_CONFIG=CA\ Toronto" \
      -e "OPENVPN_USERNAME=XXXXX" \
      -e "OPENVPN_PASSWORD=XXXXX" \
      -e "LOCAL_NETWORK=192.168.0.0/24" \
      -e "OPENVPN_OPTS=--inactive 3600 --ping 10 --ping-exit 60" \
      -e "PGID=100" \
      -e "PUID=1234" \
      -p 9091:9091 \
      --sysctl net.ipv6.conf.all.disable_ipv6=0 \
      --name "transmission-openvpn-syno" \
      haugene/transmission-openvpn:latest
  

• To make it work after a nas restart, create an automated task in your synology web interface : go to **Settings Panel > Task Scheduler ** create a new task that run /volume1/foldername/TUN.sh as root (select 'root' in 'user' selectbox). This task will start module that permit the container to run, you can make a task that run on startup. These kind of task doesn't work on my nas so I just made a task that run every minute.
