GRE Question

Is it possible to have an interface that can do GRE for a point to point IP network without having to know all the IP addressing?

I want to be able to take whatever IP address comes in on a specific GIGE interface, and ship it across the GRE tunnel to the other side, which I will then tag and forward into a specific vlan to get to its final destination. I can do this with a IPSEC VPN Tunnel, but didnt want to go down that path unless I absolutely needed to because I would have to buy an additional box to do this for wire rate speed.

Any advice, suggestions would be appreciated..
