Hi Adrian,
I think the problem might be that you connect your bankd to the server via
localhost/loopback IP. This means the server stores '127.0.0.1' as the bankd
IP and then passes it on to the client.
Simply tell your bankd to connect to a "real" IP address of remsim-server,
this way the bankd-side source address selection will also use a "real" address
and hence register that in the remsim-server instaed of 127.0.0.1
