It won't hurt to look at the Connections tab, you'll have the source/dest/ports and volumes exchanged. Or you can run tcpdump on the TUT230 but the filtering may not be easy. You can try something like:
tcpdump -i any -n -v 'not host ip_of_laptop'
or if you have a linux box around you can try:
ssh rut230 tcpdump -i any -n -U -s0 -w - 'not host ip_of_laptop' | sudo wireshark -k -i -
