SharePoint Online incoming request o On-premises servers

Hi,

 

We have two Office 365 tenant for our organization, wanted to allow incoming request to our on-premises server where some of custom application connector add-ins are hosted. But our on-premises server is behind the firewall, need to create incoming firewall rule.

 

I have checked the Ips for both of our tenant, both of them are resolving to “sharepoint.compo-0004.spo-msedge.net./13.107.136.9”.

 

Confused more. Can somebody tell m, is this static IP or dynamic. is it safe to allow incoming request from a common IP. Also please share the suggestion how to create a incoming request rule in a better way

    Senthilrajan Kaliyaperumal It is dynamic from sets of IP addresses (changes based upon where you or servers are located).
