Connecting through the proxy server

The proxy server allows you to connect to Williams-Only resources from off campus by redirecting your web traffic through a computer on campus. The proxy server will ask for your Williams username and password. This information is not passed to the site, but is used by the proxy server to grant you access.

Am I connected?

It is important to use the proxy server only when you need to access a Williams resource. If you are not accessing a restricted site, turn it off. The proxy server will make your internet connection slower, since each page you load will be filtered through the Williams network.

How do I set up the proxy server?

    • OS X, Versions 10.0+

      1. Connect to your Internet Service Provider
      2. Go to Apple | System Preferences | Network
      3. In "Location" choose "Automatic" (even if it is showing)
      4. Choose the name of your connection (e.g. AirPort or WiFi or Ethernet)
      5. Choose "Advanced"
        Mac-proxy-1
      6. Open the "Proxies" tab
      7. Check the box for "Web Proxy (HTTP)"
      8. In the "Web Proxy Server" box, type proxy.williams.edu
      9. In the next box, (after the colon) type 3128
      10. Check the box that says, "Proxy server requires password"
      11. Enter your Williams ID (unix) and password
      12. Check the box for "Secure Web Proxy (HTTPS)"
      13. In the "Secure Web Proxy Server" box, type proxy.williams.edu
      14. Repeat steps 9-11 (from above)
      15. Choose "OK" and then "Apply"
        mac-proxy-2

      To test the proxy server:

      1. Reload this page
      2. When the box pops up, enter your Williams username (without @williams.edu) and password.
        proxy-mac
      3. Click OK. Under "Am I connected?" The box should say you are connected through the proxy server.

      When you are finished using Williams resources:

      1. Go to Apple | System Preferences | Network

      4. Open the "Proxies" tab
      5. Uncheck the box for "Web Proxy (HTTP)"
      6. Uncheck the box for "Secure Web Proxy (HTTPS)"
      7. Choose "OK" and then "Apply"

      The proxy server settings will be saved, so the next time you want to use the proxy server, you'll just need to recheck the "web proxy" and "secure web proxy" boxes and click "OK" and then "apply".
