## 3.3. Configuration Steps

So far you have deployed the gateway web application in the root context of Jetty on port 8080. Since the gateway is a reverse proxy you must make sure all traffic from your browser to `http://demo.forgerock.com:8080/wordpress/` goes through the gateway. The quickest way to do this is to add an entry to your `/etc/hosts` file on UNIX systems or `%SystemRoot%\system32\drivers\etc\hosts` on Windows. See Wikipedia for more information on host files. If you are running OpenIG and the browser on the same host, add this entry to the hosts file on the OpenIG host.

If you are running the browser and OpenIG on separate hosts, you must add the IP address of the host running OpenIG. For example, if OpenIG is running on a host with IP Address of 10.0.1.5:

| Tip
Some browsers cache IP address resolutions, even after clearing all browsing data. It might be necessary to restart the browser if you are changing IP addresses of named hosts. The simplest way to make sure you have configured your DNS or host settings properly is to stop OpenIG and make sure you cannot reach the target application. If you can still reach it, you should double check your host settings. You should also make sure your name resolution is configured to check your host files before DNS. This configuration can be found in `/etc/nsswitch.conf` for most UNIX systems. Make sure `files` is listed before `dns`.
