Processor Required Ports
- Make sure that the port required by the processor is open for BOTH inbound and outbound traffic in the firewall. If not sure, disable the firewall temporarily and try again. There could be a Windows firewall, third party firewall or hardware firewall installed on your system.
- In addition, if you are restricting the IP addresses available to the network, make sure that the DNS entry for the processor's HOST can be resolved without any problems.
→ To determine the correct port and the host DNS entry, see CreditLine Processor Setup.
