What do you mean by 'disconnect'?  Do you mean you physically disconnect the
network connection (with Jetty still listening on all 4 ports), or do you mean
that you comment out the intranet listeners in the Jetty configuration and
re-start it?

Well, how much load is being created by the intranet connections?  Requests /
sec?  Average response time?

How many threads are you allowing _each_ listener to use ( setMaxThreads() )?

If the requests are arriving from both sources at roughly equal rates, I would
expect both sets of sources to be given a chance at being served. This would be
an Operating System selection, not a Jetty one.

Unless your input loading is _very_ high and _very_ strange I can't think it can
be a load balance issue.

Are the intranet requests normal, short page requests? Or are there long / large
data transfers taking place?

Are there any warnings in the Jetty Log?

It certainly ought to be able to do this.

What Operating System are you using?
Are there two physically-separate network interface cards?
