Server ports between firewalls? (Domain ports)

Hi Experts,

We are having a few issues with some ports needed open between 2 firewalls, to get the server joined to the domain. Can someone suggest the correct ports that are required.

I'm looking here:

However, this document suggests too much info for me to comprehend, currently.

Does anyone know exactly which ports are required to join a server to the domain behind a firewall. I need to open up only a select few ports for maximum security to allow this to be achievable.

Read over this for the ports needed.

I would suggest that you setup a VPN instead.

VPN is not possible here.

The are ports are required between VLANs on the same network for segregation.

I'll have a read of the ports, thank you.

Currently, this is on hold. We have enabled full IP passthrough between servers for the time being, until the exchange system is up and running. Once completed, we will log/monitor the ports and lock down there after. I'll let you know my findings..
