The Terminal IP address setting in PAYLEX Payment Services points the Cloud-based software to your Gateway IP address.
Settings>Terminals>Select a Terminal>EMV
The terminal itself has an IP address that is configured in the cloud. If the address of the device needs to change, we need to make that change for you. Then you just reboot your terminal.
The local router does the magic using a Port Forward rule (TCP and UDP) that indicates the inbound port. This is where the inbound traffic gets routed to the Local IP address of the device.
The rules look something like this (assuming a LAN gateway of 192.168.0.1 and a terminal IP address of 192.168.0.162 using port 10009).
- 192.168.0.1: 10009 --- >>> 192.168.0.162: 10009 TCP
- 192.168.0.1: 10009 --- >>> 192.168.0.162: 10009 UDP
When all three things are set, the terminal will respond with a Green Check when you execute the Terminal Query option from credit card batch settlement.
