    Hello MVP,

    What outbound ports do I need to allow open in order for WSUS to get updates
    from Microsoft? I have a DMZ which is very locked down and completely
    separated from our internal network. Rules are the WSUS server inside the
    DMZ must have some way of pulling Windows Updates without going to our
    internal LAN

  2. Firewall rule would be:

    DMZ_Server -> Internet
    Any -> 80 and 443 (TCP)

    If the DMZ server isn't using a DNS server located in the DMZ, then you will
    also need 53 (DNS)
