Microsoft online services: FQDN firewall openings
article #947, updated 1293 days ago
Some firewalls have FQDN capability (e.g., Watchguards), which makes careful rule creation practical for a behemoth like Microsoft Office 365 and all of its related services. The info below is condensed and sorted from here. I have omitted a very few items (e.g., ports 25, 143, 465, and 993, and *.msn.com), for reasons which I hope are reasonably obvious.
Create one rule with these ports:
80, TCP
443, TCP
587, TCP
3478-81, UDP
5223, TCP
50000-59999, TCP and UDP
to the following list of locations, and it is done.
*.aadrm.com *.aadrm.com *.aka.ms *.apple.com *.aspnetcdn.com *.aspnetcdn.com *.assets-yammer.com *.azure.com *.azure.net *.azureedge.net *.azurerms.com *.azurerms.com *.azurewebsites.net *.cloudapp.net *.cloudapp.net *.cloudappsecurity.com *.cloudfront.net *.edgekey.net *.edgesuite.net *.getmicrosoftkey.com *.gfx.ms *.live.com *.lync.com *.microsoft.com *.microsoftazuread-sso.com *.microsoftonline.com *.microsoftonline-p.com *.microsoftonline-p.com *.microsoftonline-p.net *.microsoftonline-p.net *.microsoftstream.com *.msappproxy.net *.msecnd.net *.msecnd.net *.msecnd.net *.msecnd.net *.msedge.net *.msft.net *.msftauth.net *.msocdn.com *.mstea.ms *.o365weve.com *.office.com *.office.net *.office365.com *.onedrive.com *.onenote.com *.onenote.net *.onestore.ms *.onmicrosoft.com *.optimizely.com *.outlook.com *.phonefactor.net *.sfbassets.com *.sfx.ms *.sharepoint.com *.sharepointonline.com *.skype.com *.skypeassets.com *.skypeforbusiness.com *.sway.com *.sway-cdn.com *.sway-extensions.com *.tenor.com *.trafficmanager.net *.trafficmanager.net *.virtualearth.net *.visualearth.net *.visualstudio.com *.windows.net *.windowsazure.com *.windowsazure.com *.yammer.com *.yammerusercontent.com ajax.googleapis.com ms.tific.com

LAN firewall settings for G Suite services
article #1119, updated 1705 days ago

The above are all on port 443, HTTPS, only. There is a legacy product which uses talk.google.com on port 5222, XMPP.

United Parcel Service and Firewalls
article #1019, updated 1979 days ago
A page has been recently deleted from the UPS web site, which included:
If I connect to UPS servers through a firewall, are there any known issues?
Because the response from the UPS server may show as unsolicited to your firewall software, you may need to configure your firewall software to accept messages from our unique range of UPS IP address ranges: “207.24.0.*”
At this writing, an in-site search on http://ups.com and a Google search still brings up the page reference, but the page is gone.
