MS O365 ip address range

L4 Transporter



Any one know if PA have a dynmic range that covers MS ip address range.


Seems like the sort of thing that would be easy to implement and would save me a lot of time.



L4 Transporter

minefield seems to be the way forward.


Had a chat with my SE on this and the fuel user group pointed to this


I thought I'd comment for anyone reading this who doesn't have the systems to implement Mindmeld, and is looking for an on-prem Windows solution.


Microsoft has a powershell method of getting the latest o365 IP Addresses into a text file. You can then host that file on an IIS server, script Powershell to keep it up to date and point a PAN EBL at this file.  Works great.  One catch, the Microsoft Powershell script puts CR-LF at the end of each line and apparently EBL can only handle LF.  So you'll need to edit the powershell script and add this line after the out-file statement:   (Get-Content $datapath -Raw).Replace("`r`n","`n") | Set-Content $datapath -Force   


That will replace the CRLF with just LF.


Script from MS is here


I posted a Linux scripted solution a few weeks back in response to another query on he EDLs.


We briefly looked at mindmeld.
