 In this example, the `my-nginx-proxy` container will be connected to `my-network` and `my-other-network` and will be able to proxy to other containers attached to those networks.
 
+### Custom external HTTP/HTTPS ports
+
+If you want to use `nginx-proxy` with different external ports that the default ones of `80` for `HTTP` traffic and `443` for `HTTPS` traffic, you'll have to use the environment variable(s) `HTTP_PORT` and/or `HTTPS_PORT` in addition to the changes to the Docker port mapping. If you change the `HTTPS` port, the redirect for `HTTPS` traffic will also be configured to redirect to the custom port. Typical usage, here with the custom ports `1080` and `10443`:
+
+    $ docker run -d -p 1080:1080 -p 10443:10443 -e HTTP_PORT=1080 -e HTTPS_PORT=10443 -v /var/run/docker.sock:/tmp/docker.sock:ro nginxproxy/nginx-proxy
+
 ### Internet vs. Local Network Access
 
 If you allow traffic from the public internet to access your `nginx-proxy` container, you may want to restrict some containers to the internal network only, so they cannot be accessed from the public internet.  On containers that should be restricted to the internal network, you should set the environment variable `NETWORK_ACCESS=internal`.  By default, the *internal* network is defined as `127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16`.  To change the list of networks considered internal, mount a file on the `nginx-proxy` at `/etc/nginx/network_internal.conf` with these contents, edited to suit your needs:
