I can get new mail notifications over a Cisco VPN without problems. Are you
filtering the VPN traffic? If so allow outbound UDP from your Exchange

Um, no.

There's no new mail notify over our Cisco VPN system, but we have another
legacy system that allows those packets through.  I'm trying to do research
so my network guys have something to work with.
