We recently entered into a contract with a new payment processor. The credit card machine communicated via telephone line or Internet. We have a Cisco ASA 5505 security appliance. Using the Cisco ASDM control interface, I would like to set up permission for two specific ports, one outgoing and one incoming, specified by the payment processor. I am unsure as to how to configure the rules or exceptions for the two ports. I have made several attempts but the device still reports a communications error. If I bypass the ASA box, the device has no issue communicating with the payment processing service. Thanks!
