Our service may not function properly if firewalls prevent some of our own and/or merchant components from communicating. 
All necessary information are provided in this document to help configure the merchant's firewalls and minimise communication errors between the merchant's network infrastructure and our payment gateways.
This document assumes that the merchant is familiar with the procedures for configuring firewalls, routers or any other devices used to block traffic on the merchant’s network.
