The configuration on the Router and concentrator would still remain the same.

If you have a router in front of the concentrator, that means you shud have a NAT (static) entry defined for concetrator Public Intf ip address.

The remote router will use that Public ip address of the conctrato create the tunnel. Also, on the local Router, please make sure you have following ports opened :

UDP 500

UDP 4500


Hope this answers your questions.
