Open port numbers on firewall
OneSpan Authentication Server uses several different ports to communicate (see Incoming ports used by OneSpan Authentication Server and Outgoing ports used by OneSpan Authentication Server). If these are blocked by a firewall, some features will not work correctly.
Before installing OneSpan Authentication Server, ensure that these ports are open and not in use. The Installation Wizard will issue a warning and halt the configuration process if any of these ports are unavailable.
We recommend using a software firewall on OneSpan Authentication Server and segmenting the OneSpan Authentication Server network with a hardware firewall.
