I know that the usual way for a lan to lan connection to work is to set up a connection from a private side host/network to a private side host/ network on the other end, but is it possible to set up the VPN to communicate to a host that is on the same network subnet as the public interface? In other words, I have a host on the DMZ that I want a remote network to communicate with only through the VPN, Is this possible?

Hi there,
It really depends on the VPN device that you are using. Using the Cisco IOS router, VPN3K concentrator, VPN5K concentrator it is possible. If you are using PIX as the VPN peer, then it is not possible
Hope that helps

I guess I should have been more specific, but yes, on my side is a 3002 concentrator in which the server is on the same public network (DMZ). And the remote network is a PIX. Im kind of confused on your answer though, are you saying that if the remote peer is behind a PIX trying to get to the Public host in the same network as the Concentrator it wont work?
Thanks

Hi there,
If the server is on the public subnet of a 3002, then it will not work
3002 is not really a VPN concentrator. It is actually a HW client. It only established an IPSec tunnel between its private subnet the Network-list that the remote VPN server is pushing down
As far as your pix question is concerned, if the server resides on the outside interface of the pix ( the interface where you are terminating your tunnel ), then it is also not possible
Hope that clarifies

Im sorry, its not a 3002 HW client, but a 3000 series concentrator. DUH!! But im assuming that it will work then from your response. I did do some pre- testing set up and specified the IP address of the public server in the local network settings for the site to site tunnel properties, and it didnt error out or anything, and it took the config. Thanks for the response, and I'll let you know how it goes. Sorry about the brain hiccup! :-)
