# Firewall Configuration

The Payment Device SDK must be able to communicate with CardEaseXML (<https://live.cardeasexml.com>) and CardEaseTMS (<https://tms.cardeasexml.com>) on the payment gateway platform. This may require changes to your firewall configuration.

The table below lists the IP addresses and port numbers for each external service used by the SDK.

## *Table 4 - IP addresses and port numbers for external services.*
