Port Communication Requirements

Active Directory

For EmpowerID to communicate with Active Directory environments, the following ports must be open:

135/TCP RPC
137/UDP NetBIOS
138/UDP NetBIOS
139/TCP NetBIOS
389/TCP/UDP LDAP
636/TCP LDAP SSL
3268/TCP LDAP GC
3269/TCP LDAP GC SSL
53/TCP/UDP DNS
88/TCP/UDP Kerberos
445/TCP SMB
123/UDP NTP

Internal EmpowerID Communications

The EmpowerID Management Console Windows desktop client requires the following ports be open:

HTTPS/TLS: port 443 TCP

EmpowerID server to server communications require the following ports be open:

HTTPS/TLS: port 443 TCP

EmpowerID server to SQL Database communications require the following ports be open:

Microsoft SQL Server: port 1433 TCP

The EmpowerID WAM/Reverse Proxy does not require any communication with the Microsoft SQL database. The Reverse Proxy retrieves all of its configuration data by calling the EmpowerID REST API on any front-end servers.

The below two images depict the EmpowerID Communications and Connectivity architecture. The first shows the architecture without EmpowerID WAM/Reverse Proxy, while the second shows the architecture with EmpowerID WAM/Reverse Proxy.

In addition to the above, for password resets you may need to open TDP/UDP 135, as well as all RPC dynamic ports. For more information, see the following Microsoft topics:
