We are seeing weird issues with our credit card processing. Within our software we can attempt an authorization to paypal payflow. On the first try it fails on the second it goes through.
The server is running in a VLAN environment and has access to the internet but this seems to have started after setting a new vlan, which I am not sure if it has anything to do with it. The IBM trace shows a SYN but no ACK The sonicwall shows we are forwarding it but not receiving any information. I am confused and have exhausted all my thoughts.
The server is an IBM AS400
If the server has access to the internet and is processing am I correct into thinking this is not a network issue?
