Power BI data gateway communication protocols and ports required

[MayAS]

The Power BI security whitepaper indicates that if https is used for communication then you only need to open outbound port 443. Can someone confirm that for me please?

This part is from the Power BI security whitepaper:

• The gateway supports the following two communications protocols:

  • AMQP 1.0 – TCP + TLS: This protocol requires ports 443, 5671-5672, and 9350-9354 to be open for outgoing communication. This protocol is preferred, since it has lower communication overhead.

  • HTTPS – WebSockets over HTTPS + TLS: This protocol uses port 443 only. The WebSocket is initiated by a single HTTP CONNECT message. Once the channel is established, the communication is essentially TCP+TLS. You can force the gateway to use this protocol by modifying a setting described in the on-premises gateway article.

Hi @MayAS ,

That is my understanding thta only port 443 for OUTGOING needs to be opened.  I guess the only way to know for sure for sure would be to create a ticket and get Microsoft to confirm that to you.

I would appreciate Kudos if my response was helpful. I would also appreciate it if you would Mark this As a Solution if it solved the problem. Thanks!
