Network, Firewalls & Proxy configuration of 365 MP

Question

Hello All,

Thanks in advance.

I have a requirement to configure O365 MP.

I have a doubt on the Network, Firewalls & Proxy configuration of 365 MP. As per the MP guide --> This article provides details about the specific network requirements to connect to Microsoft 365 services:
https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide#bkmk_teams

How can i ensure the mentioned Network, Firewalls & Proxy requirements are satisfied with a manual check.

My watcher Node is having an Internet access.

Thanks & Regards,
Anupvtr

Answer 1

Hi Anu,

that is correct. You have to confiigure the prioxy for:

1. Configurations (Wizard)
2. Monitoring
3. Watcher Nodes

Also to this:

> First proxy configuration needs to be performed on console servers basically on all Management servers.-->Whether it will create any issue for other monitoring functionality
Second proxy configuration needs to be performed on MS. That means i need to perform the edit on all SCOM MS -->Whether it will create any issue for other monitoring functionality
Third one is on Agent Server Watcher node.

This is absolutely correct, as per the guide.

Hi @ANU ,

you want to do a manual check of all the requirements, if I get this right?

I would say that you can start testing all the ports with PowerShell or any other tool. Let take the first set of ports:

You can start testing those, using "Test-NetConnection" or build a script that will go over all those ports and addresses:

If you want my honmest opinion: This is not your thing to worry about, but this should be taken care by your networking team. You just need to forward them those addresses and the ports and they will have to take care of opening those and ensuring that the communication can be established.

@SChalakov Thanks for the help.

As per the network team update "It should be reachable via the proxy". The watcher node server have the internet access

I am not quite sure about how to add the proxy. Is this the same proxy mentioned in the MP document.
