Vpn on Cisco 2811

Does anyone know if I can configure the VPN server between the two built-in ethernet ports?
Is there a design/hardware reason why this can't be done?

You can't do it because of connected routes.

Since the router knows about both interfaces, you can't get the router to route traffic out interface "A" that has a destination address for interface "B".

If you tell us the reason you'd want to do this and the application, maybe we can suggest a workaround.

I've recently moved to an MPLS solution for Phones and Internet where the provider manages firewall duties. I could eliminate the 2811 entirely except that the VPN is less expensive than the providers'. Now I have no WAN connection directly to the router. I'd still like to run the VPN however. The only way ( if possible) I could see to do this is to use a separate public IP NAT'd to an internal subnet and attached to FE0/1 than use FE0/0 connected to internal network with VPN running in between. Unfortunately even allowing for firewall ports opened for CISCO VPN, I'm still unable to connect. Now wondering if I can even do such a trick...
