The decision to use ESP versus UDP is out of my hands since we are connecting
to a client's VPN.  However, since I have more information about the likely
cause, I may be able to get them to accomodate our "special" situation.

As a previous poster suggested: using static address mapping.  If you have
more
than a handful of PCs using the client, this could be a nightmare
though.  Is there
some reason you're unwilling (or unable) to use UDP?  It's a far better
solution! (and
is why VPN providers have been migrating that way...)
