Hi guys,
This is my configure that route Vlan 40 To AD.
I'm planning close all ports and open specific ports for AD authentication, Windows File Share. I opened TCP/UDP 445, 389, 137, 138, 53, 88
My problem is Users can't login into domain's client, it said wrong pass user/pass, same error with Windows File Share. But when i open all port on Firewall rule, domain's clients can login again. I think That rule block authentication user on AD.
Didi miss any port need to open on firewall ?
Regards.
