Mark,
In the package vpnc, there is an option to specify custom routes (taken from
the man page):
Custom route setting
By default, the default route is deleted after connection and
replaced with the new one (going trough the VPN tunnel device).
However, some people wish to limit the target address range to
few IP ranges. This can be done using the config directive
Target networks in the config file. For example:
Target networks 123.234.210.0/24 10.1.0.0/16
In the file vpnc-connect they use ip directives to specify particular routes.
You may want to install this package and take a look at how they specify the
routing. Mimic what they do in vpnc-connect as far as routing goes and see
if that doesn't solve your problem.
