Possibly you need to use -query -from <corresponding local IP for
the subnet containing that IP address>

Xming has a patch applied which adds some more intelligence to the way the
local IP address is chosen, but unfortunately that is written to use the
winsock API directly, so can't be used directly in XWin.
