Perhaps right-clicking the NM icon -> edit connections -> select the
correct wired connection -> edit -> IPv4 settings -> Routes... -> 'Use
this connection only for resources on it's own network' check box will
tell NM to route global traffic back to the 3g connection.
Word of warning though, getting caught using a modem while connected to
the office lan by high strung security obsessed network/IT guys might
mean losing your job.
