Mark I was having the same issue a few months ago. I then download configmaker from cisco and put together a senario, and then transferred the senario over to my lab. It worked, I was then able to go back and pick apart the configs and figure everything out. I know it's like putting the cart before the horse, but in this case it did work.

I've been challenged with putting a VPN together between two sites, and it shouldn't be a problem, as it seems to be a straight forward config, and I've used the example off of CCO. The problem is, I can't seem to pass traffic successfully across the VPN. :( Attached is the config for both ends of the network setup. As far as I know, as long as I've met the following criteria, this should work: 1. Both ends have to have a public static address for at least the Router. 2. Either end can have a static NAT for an extra inside host, such as a WWW server. 3. The VPN tunnel should work, no matter what type of "outside" interface the Crypto map is applied to; if regular private to public net connectivity works using NAT Overload, then End to End Tunnel termination should work so long as the access-lists are done right. This being said, this is what I got from CCO: ASCII Diagram of network scenario LAN(192.168.10.0) -- RouterHQ --(WIC1-ADSL) DSL --Internet-- SL --RouterBranchOffice--LAN (192.168.1.0) RouterHQ is assigned 5 public IPs, one assigned to the Router, 1 assigned to WWW Host via Static NAT RouterBO is assigned on public IP, which is assigned to the Router, with NAT Overload running for the hosts on the private LAN. * The description and ASCII art has been slightly modified from the CCO example only to use a WIC-1ADSL as the "Outside" interface on the HQ Router, rather than Ethernet Interfaces.
