DC synchronisation port

[Arnaud BALAY \(ZKM\)]

Hi,

I have 2 sites with 2 different networks (site 1: 10.10.40.0/255.255.252.0 &
site 2: 10.10.44.0/255.255.252.0) linked by a router.
On site 1 there is a PDC (10.10.40.5) of domain "DOMAINE1" and on site 2
there is a BDC (10.10.44.5) of the same domain.
For security reason, I need to grant access to the minimum IP/Ports on the
router to allow :
1) PDC & BDC synchronisation
2) Site 1 users can use PDC & BDC (domain & netlogon)
3) Site 2 users can use PDC & BDC (domain & netlogon)

Could you tell me what are the required rights to enter into the router.

Thanks for your help
