 You can also use wildcards at the beginning and the end of host name, like `*.bar.com` or `foo.bar.*`. Or even a regular expression, which can be very useful in conjunction with a wildcard DNS service like [xip.io](http://xip.io), using `~^foo\.bar\..*\.xip\.io` will match `foo.bar.127.0.0.1.xip.io`, `foo.bar.10.0.2.2.xip.io` and all other given IPs. More information about this topic can be found in the nginx documentation about [`server_names`](http://nginx.org/en/docs/http/server_names.html).
 
+### Multiple Networks
+
+With the addition of [overlay networking](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) in Docker 1.9, your `nginx-proxy` container may need to connect to backend containers on multiple networks. By default, if you don't pass the `--net` flag when your `nginx-proxy` container is created, it will only be attached to the default `bridge` network. This means that it will not be able to connect to containers on networks other than `bridge`.
+
+If you want your `nginx-proxy` container to be attached to a different network, you must pass the `--net=my-network` option in your `docker create` or `docker run` command. At the time of this writing, only a single network can be specified at container creation time. To attach to other networks, you can use the `docker network connect` command after your container is created:
+
+```console
+$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
+    --name my-nginx-proxy --net my-network jwilder/nginx-proxy
+$ docker network connect my-other-network my-nginx-proxy
+```
+
+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.
