  1. Enable anonymous access for a web application from the Central Admin.
    - Central Administration Home Page > Application Management > Authentication Providers
    - Select the web application where you want to enable anonymous access
    - Click the "default" Zone
    - Mark the checkbox "Enable anonymous access"
    You don't have to do anything on the IIS Manager. Enabling it from the Central Admin page will also enable it on IIS and modify your web.config.

  2. Explicitly turn it on for the sites you want to be accessed anonymously.
    Browse to your site, click Site Settings > Advanced Permissions > Settings >Anonymous Access and turn on anonymous access for the site.

  3. For further settings search your Sharepoint help for "enable anonymous access".
