Configure Open Firewall Ports

Digipass Authentication for Windows Logon communicates through TCP/UDP ports. If these are blocked by a firewall, some features will not work correctly. Before using Digipass Authentication for Windows Logon or if you experience issues, verify that the relevant ports are not blocked by a firewall.

If you upgrade from Digipass Authentication for Windows Logon 1.4 and have a custom SEAL port configuration, i.e. a SEAL port other than 20004, the custom port is preserved and used for the SOAP connections as well. If you have implemented a firewall or some routing or port forwarding mechanism, you may need to update your configuration.

For information about firewall ports required by OneSpan Authentication Server, refer to the OneSpan Authentication Server Administrator Reference.
