Résumé de l’article

OneSpan Authentication Server Appliance uses several different ports to communicate (see Table: Incoming ports used by OneSpan Authentication Server Appliance and Table: Outgoing ports used by OneSpan Authentication Server). If these are blocked by a firewall, some features will not work correctly.

We recommend using a software firewall on OneSpan Authentication Server and segmenting the OneSpan Authentication Server network with a hardware firewall.
