We have a 100% isolated environment that needs to communicate with our AD infrastructure outside the isolated environment. I need to know all the ports and whether they're incoming or outgoing. These are the ports I've gathered so far. Can anyone help adding any that might be missing and the inbound / outbound direction. Thanks so much! (These are separated via physical firewall).
- TCP 135 : MS-RPC
- TCP 1025 & 1026 : AD Login & replication
- TCP 389 : LDAP
- TCP & UDP 53 : DNS
- TCP 445 : SMB , Microsoft-ds
- TCP 139 : SMB
- UDP 137 & 138 : NetBIOS related
- UDP 88 : Kerberos v5
- TCP 636: Secure LDAP
- TCP 3269: Secure LDAP
