This is how I understand the problem:

Home connects to vpn1 at work, creating a tun1 device.  Problem is
that vpnc doesn't create a default route to vpn1.  Point is that I
don't want EVERYTHING going through tun1, because that would cause
problems with mail traffic coming from other places (this is my home
network gateway).

Once I set up routes to the vlan that Work belongs to, setting up the
IP given to tun1 as the gateway, Home can connect to work.

Problem is that the default route still goes to tun0 (my dsl device)
which cannot change without interfering with all other traffic into
the box.

The question is can I set things up so that Work will come through the
VPN pipe to get to Home?

I'm starting to think I can't.
