• BLOCK_PORTS -- Block outbound ports. e.g. BLOCK_PORTS="4646 5050"
• CIPHER -- defaults to AES-256-CBC
• DNS_1 -- primary DNS when PUSH_DNS is true (defaults to 208.67.222.222)

Examples

These examples assume that all files described above that can be host-mounted are host-mounted or added with a derivative Dockerfile.

Route all traffic.

docker run -d \
   -e BIND_PASSWORD="foobar" \
   -e DOMAIN="mydomain" \
   -p 1194:1194 \
   --cap-add NET_ADMIN \
   --device /dev/net/tun \
   avinson/foxpass-openvpn

Route only the subnet 10.128.0.0/16 through the VPN. Restrict to the "engineer" group.

docker run -d \
   -e BIND_PASSWORD="foobar" \
   -e DOMAIN="mydomain" \
   -e GROUP_FILTER="engineer" \
   -e PUSH_DNS="false" \
   -e ROUTE_ALL_TRAFFIC="false" \
   -e ROUTE_SUBNET="10.128.0.0 255.255.0.0" \
   -p 1194:1194 \
   --cap-add NET_ADMIN \
   --device /dev/net/tun \
