    This is still the official list:

    https://support.office.com/de-de/article/urls-und-ip-adressbereiche-von-office-365-8548a211-3fe7-47cb-abb1-355ea5aa88a2

    MS provides this enormous list of IPs and subnets in some crazy format or XML. I counted 343 entries!!! Do they really know, they need all of these?!

    Seems to be more secure, to use a list of FQDNs. But how can I use FQDNs with wildcards like *.office365.com to alias and use them in the pfSense firewall rule set?

    I found one posting, someone used Robtex.com to translate a much shorter list into IPs. But that seems not feasible by sheer amount.
    Any suggestions?

      You can't. If you want to know why, research how a domain alias works.
