Support Remote Access

TeamViewer is an application that lets Pitney Bowes Service access your device remotely, when you authorize it. (A TeamViewer session can only be initiated by someone on your end, therefore the system cannot be accessed without your knowledge.)

There are two ways to unblock TeamViewer:

  • General unblocking of Port 5938 TCP for outgoing connections (recommended). Port 5938 is only used by a few applications and therefore there is no security risk. This traffic should be filtered or cached.
  • Unblocking URLs of the following formats (to any server) GET:
    • /din.aspx?s=…&client=DynGate…GET
    • /dout.aspx?s=…&client=DynGate…POST
    • /dout.aspx?s=…&client=DynGate…

Note: Regardless of which method you choose to unblock TeamViewer, verify there are no content filters or anything similar blocking one of these URLs:
