I was going to mention at the club if it could be your policy rules
interfering.  It didn't occur to me it could be them being routed
around.  :-)

Could #CC2 be switching to your laptop's MAC address?

How about leaving the mouse to continue his excursions, but see if you
can monitor traffic levels over time by MAC or IP address on the
Draytek.  Or if the Draytek doesn't offer that, on Golux, if all traffic
must pass through it to reach the Draytek.  That might give a clue as to
what's being spoofed?
