### 8.3.6. Gateway Configuration

See Installing OpenIG for instructions, and have your container listen on port 8080. Install OpenIG in the root context by removing the existing root context directory `$HOME/tomcat/webapps/ROOT/` and then renaming the OpenIG .war to `$HOME/tomcat/webapps/ROOT.war`.

Download the WordPressDecryptHeaderLogin.json configuration file, and use it to replace `$HOME/.ForgeRock/OpenIG/config.json`.

Search for and replace `DESKEY` with the key generated when you enabled the password capture feature in OpenAM.

Restart OpenIG after making changes to `config.json`.
