Hello Phil,
We are sorry to hear that it isn’t transferring through to the system. There are a couple stand out things here that may be cause this. First and foremost, the big one is Win 11 we do not expect Windows 11 to work with Ra2 and would highly suggest getting or borrowing a Windows 10 PC before proceeding any further with the attempted transfer.
Secondly even if the firewalls are turned off sometimes there is other software getting in the way. We would suggest taking a look at the Networking guide and following the section that calls out Firewalls on pages 21 through 23. That section there will show you how to set up your inbound rules so they will not effect your Ra2 software. Here is the link for the Networking guide;
