 Note that [not all regions support port forwarding](https://www.privateinternetaccess.com/helpdesk/kb/articles/how-do-i-enable-port-forwarding-on-my-vpn).
 
 When `PORT_FORWARDING=on`, a port will be forwarded on the VPN server side and written to the file specified by `PORT_FORWARDING_STATUS_FILE=/forwarded_port`.

 It can be useful to mount this file as a volume to read it from other containers, for example to configure a torrenting client.
 
-## HTTP control server
+You can also use the HTTP control server (see below) to get the port forwarded.
 
-A built-in HTTP server listens on port `8000` to modify the state of the container. You have the following routes available:
+## HTTP control server
 
-- `http://<your-docker-host-ip>:8000/openvpn/actions/restart` restarts the openvpn process
-- `http://<your-docker-host-ip>:8000/unbound/actions/restart` re-downloads the DNS files (crypto and block lists) and restarts the unbound process
-- `http://<your-docker-host-ip>:8000/openvpn/portforwarded` to get your port forwarded as JSON. You can use **jq** to parse JSON on linux.
-- `http://<your-docker-host-ip>:8000/openvpn/settings` to get your openvpn settings as a JSON object.
