# Nexus Repository 3 Pro Setup

To set up Repository Firewall for your Nexus Repository, you need to connect to the Firewall server in Nexus Repository Administration and enable the Firewall capability on your proxy repositories.

Use the following steps for Nexus Repository 3 Pro:

1. Select `IQ Server` from the `Settings` menu

2. Complete the IQ Server setup form
   1. Select the `Enable the Use of IQ Server` box
   2. Add your IQ Server URL
   3. Select an authentication method
      1. User Authentication: enter the IQ Server username and password
      2. PKI Authentication: delegate to the JVM for authentication
   4. Select `Save`
3. Select `Verify Connection` to test the configuration

**Note**  
We recommend using a dedicated service account (a local IQ Server user reserved for this integration) when connecting Nexus Repository to the IQ Server in production environments. Consider generating user tokens as an added layer of security.

At a minimum, this account requires access to the Evaluate Individual Components permission at the Repository Managers level in Firewall Repos and Policies.

Leave the following configuration options blank unless directed by Sonatype support:
