Does anyone have any experience with a setup similar to the following?

----------------   -----------------  ppp to internet
| Non-routable |---| FreeBSD PPP   |------------------{-}
| Private LAN  |   | Gateway (NAT) |                   |
----------------   -----------------                   |
                                                 ----------------
                            -------------        |  Cisco VPN   |
                            | Corporate |--------| Concentrator |
                            | LAN       |        ----------------
                            -------------

Ideally normal Internet traffic would just be NATed and sent through the
ISP,
while certain traffic would go through an IPSec tunnel to the corporate LAN.

Currently, I have the BSD box (4.1-STABLE) configured as a PPP NAT gateway
for the private LAN using ppp's nat and ipfw.

I appreciate any insight anyone can provide.  Thanks.
