Deploy ASA (for site-to-site VPNs) across DMZs?

[a.wheeler]

We are replacing cisco concentrators with ASAs to support site-to-site VPNs.  The concentrator(s) are currently deployed across DMZs (public interface on less secure DMZ and private interface on more secure DMZ).  Is it possible to configure the ASA (will be in failover mode) in the same fashion?  I have been unable to find any examples/discussion of this sort of design.  Thanks for your input, Anne

I am not sure I understand how your VPN is currently set up and how you want it to behave...could you explain in more detail how this is set up? please add a network diagram too as to how this all connects together.
