Proxy Server Setup for Tehama Desktops

You may wish to set up your Tehama Desktop to use a proxy server (software that intercepts traffic between your desktop and a remote endpoint).

Running a proxy server on your Tehama Desktop will interfere with functionality that is necessary for your Desktop to run properly, unless you take steps to make sure that your proxy server excludes the following IP addresses:

  • 1.0.0.0
    (DNS, load balancer)
  • 169.254.169.254
    (Amazon EC2 metadata server)
  • z.arin.net
    (reverse lookup)
  • N.N.*.* syntax for Windows or N.N.0.0/16 syntax for Linux,
    where N.N are the first two segments of your desktop's IP address.
    (local (intranet) addresses)

To accomplish this:

  1. First Find your Desktop IP Address.
  2. Then:
