Sure, you should be able to do that. With L2TP/IPsec the client gets
assigned an IP address in the same subnet as the other (internal)
network interface. You can bind the webserver to that interface
so that it is not directly accessible from the external interface.

For a demo setup you don't even have to use certificates, a PSK
should be fine as well.
