Re: AD Trusts and Firewall

I've seen this document but I do not know between which machines these
protocols should be opened.
In my case shall the 2 domain controllers behind a firewall be able to
communicate with the Root domain or only with one DC of the Child ?

Regards and thanks for you help

Hi,
I've got some questions concerning Trusts and Firewalls. (I hope my
explanation will be clear).
I have an Active Directory Forest (ad.local) with an empty root domain
(ADROOT)
2 domain controllers are installed for this root domain.
I have a child domain (d1.ad.local) with 2 domain controllers.
This child domain is trusted with other Windows domains for migration
purposes.

I need now to install some Domain controllers on other sites protected
with
firewall where I will need to add some trusts with their local domain for
migration purpose.

What are the firewall rules to be added between each of these elements
(For
the Moment nothing is opened) ?

Best Regards

This can be summarized like
ADROOT
|--DC1
|--DC2
|
Legacy Domains-/Trust/- D1.ad.local -/FW/--- -/Trust/- Legacy
Domains
|-DC3 |-DC5
|-DC4 |-DC6
| |
