 Set the environment variables for _openconnect_ in the `.env` file again (or specify another file) and 
 map the configured ports in the container to your local ports if you want to access the VPN 
 on the host too when running your containers. Otherwise only the docker containers in the same
 network have access to the proxy ports.
 
+# Route traffic through VPN container
+
+Let's say you have a `vpn` container defined as above, then add `network_mode` option to your other containers:
+
+	depends_on:
+	  - vpn
+	network_mode: "service:vpn"
+
+Keep in mind that `networks`, `extra_hosts`, etc. and `network_mode` are mutually exclusive!

 # Configure proxy
 
 The container is connected via _openconnect_ and now you can configure your browser
-and other software to use one of the proxies (8888 for http/s or 8889 for socks).

 For example FoxyProxy (available for Firefox, Chrome) is a suitable browser extension.
