Desktop Proxy Setup

You may wish to set up your Tehama Desktop to use a proxy server.

To prevent the use of a proxy server from interfering with the desktop functionality, it is necessary to whitelist the following IPs:

  • 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)
