With the introduction of Internet communication for payment terminals, vendors and acquirers have to consider that firewalls might block the outgoing traffic from the terminal over the router infrastructure of the merchant to the acquirer. In that case the terminal will not be able connect the acquirer’s systems over the ADSL or cable broadband connection.

Parties on the Internet are identified with IP addresses. Firewall settings involve the declaration of IP addresses the terminal is allowed to access and require a local setup for individual routers installed by or on behalf of merchants. Firewall settings can also be defined at the level of managed Internet networks, such as the GPRS service for mobile communication.
