Have a look at this  GotDotNet User Sample: Asynchronous Trace Route
(tracert) in C#

The link is:

because you know your internal subnet you should be able to detect your
router external IP as soon as it changes while running the tracert.

I have not tested the code with mono, but this should work. Let me know if
it works for you.
