I am going to implement Secure Duo for Microsoft RDP on my customer’s site. I need to know the exact port requirement or firewall requirement in order for Secure Duo to work for their Windows server (Push Notification).
My customer is a bank, therefore, they are careful with these firewall and ports opening.
Please advise.

Hi @boonz ,
Please see the following KB article: Which port does Duo Authentication for Windows Logon use to send and receive responses to and from the Duo cloud service?
Cheers!

Hi DuoPablo,
Is the destination https://duo.com? Need to provide the exact destination to customer for them to allow tcp 443 from the firewall side.

The destination is the API Hostname that you configured during Step 2 of Duo Authentication for Windows Logon and RDP | Duo Security
