  • Hello,

    Clients communicate with WSUS server over port 8530 by default. I want to confirm if you have customize the port number during setup.

    And telnet is used to test if the port is blocked by firewall..

  • Hi,

    The default port for WSUS 6 is 8530. So is 8350 a typo or a costomized port?

    Can you telnet that port?
