FAQ

Here we collected the most frequently asked question from our users and prepared answers to them. We aim to update the page quite often. So, if you didn't find the answer to your question, make sure to come check this page later. Or, you can ask you question directly in our support chat via Facebook messaeger widget on the main page.

• How much does your product cost? 

  Our open-source VPN server is absolutely free to use.
• What do I do if can't download config? 

  If your DockoVPN server is running, but you can't download config, then most-likely you have Firewall settings that prevent you from downloading client config via port DockoVPN uses for serving configs. To fix that, try to disable Firewall, for istance, on Ubuntu you can run:
  
  

  ufw disable
  Copy

  
  If by some reason disabling Firewall isn't an option for you, you can try to use different config port.
• Is it possible to change default DockoVPN ports? 

  You can change default ports DockoVPN serer uses. To do so, use following snippet:
  
  

  DOCKOVPN_CONFIG_PORT=<custom config port>
  DOCKOVPN_TUNNEL_PORT=<custom vpn port>
  docker run -it --rm --cap-add=NET_ADMIN \
  -p $DOCKOVPN_TUNNEL_PORT:1194/udp \
  -p $DOCKOVPN_CONFIG_PORT:8080/tcp \
  -e HOST_ADDR=$(curl -s https://api.ipify.org) \
  -e HOST_CONF_PORT="$DOCKOVPN_CONFIG_PORT" \
  -e HOST_TUN_PORT="$DOCKOVPN_TUNNEL_PORT" \
  --name dockovpn alekslitvinenk/openvpn
  Copy

  
  Make sure to replace <custom config port> and <custom vpn port> with real port numbers you need.
• How do I create a new client config? 

  In case you need to create a new client config config, you can use snippet below:
  
  

  docker exec dockovpn ./genclient.sh z 
  Copy

  
  The code above will generate a new client configuration, package it into a zip archive and serve it via a one-shot web-server.
• How do I revoke client config? 

  To revoke client config you need to know client Id of the config you want to revoke. You can find it in the config itself:

  

  Once client Id is know, you can run the following command:
  
  

  docker exec dockovpn ./rmclient.sh <client id>
  Copy

  
  Make sure to replace <client id> with real client Id you intend to revoke.
• How do I make DockoVPN bind to a different network interface? 

  By default DockoVPN binds to eth0 network interface, but you can overide this behaviour by supplying NET_ADAPTER environment variable to container. Se snippet below:
  
  

  docker run -it --rm --cap-add=NET_ADMIN \
  -p 1194:1194/udp -p 80:8080/tcp \
  -e HOST_ADDR=$(curl -s https://api.ipify.org) \
  -e NET_ADAPTER=<network interface> \
  --name dockovpn alekslitvinenk/openvpn
  Copy

  
  Make sure to replace <network interface> with real network interface you intend to use.
• Which VPN protocols do you support? 

  At the moment we support only OpenVPN protocol. We plan to add support to Wireguard and IKEv2 soon as well.
