static route through vpn

[spookycave]

I have a pix525/unrestricted with 3 interfaces - inside, outside, dmz. On the dmz interface I have a router, behind which is a server with ip address 172.x.x.x. On the inside interface, client computers connect to the server at 172.x.x.x, so I set up a static route for the server's ip address pointing to the router on the dmz interface. This works great.

What doesn't work is when a vpn client user connects to the pix and tries to access the server at 172.x.x.x. The static route doesn't appear to work for the vpn client user, even though he has an ip address on the inside network. What am I missing here?

Thanks 1,000,000.
