We’re trying to move all our DNS records to Cloud Flare however have run into an issue because our payment gateway SecurePay doesn’t use IPV6. It is in part related to this issue however SecurePay have said their platform has changed since then.
Basically about half of our transactions were failing because of an Invalid IP address.
I have tried to get help from SecurePay on this but am at a bit of a loss on what settings need to be changed.
SecurePay have advised that it needs to be IPv4 - I tried Add Header in Pseudo IPv4 setting but this did not fix the issue.
The last correspondence SecurePay provided was this:
Please be advised that our level 2 team has suggested that your payments have been passing through an invalid IP address which we do not support .(Please find more information in the XML API guide URL : https://auspost.com.au/payments/docs/securepay/resources/Secure_XML_API_Integration_Guide.pdf - in Page 19)
Any assistance would be greatly appreciated.
