Quick questions. I've been reviewing the guides on Cisco and have yet to find an example of what I'm looking for. The scenario is that there will be a client device that uses DHCP on the WAN side. This device can authenticate using IPSec to a VPN termination device. On our hub end we want to use a Cisco IOS router to terminate the connection. My question is that this will not be exactly a L2L tunnel, the endpoint has a configuration to build in a username to authenticate with. So it appears the tunnel with authenticate using a username a pre-shared key, rather than PSK and configured remote IP address (since this is DHCP). I've found an example of this on Cisco here: http://www.cisco.com/en/US/products/hw/vpndevc/ps2284/products_configuration_example09186a00800ae459.shtml. Unfortunately the example is from an IOS DHCP endpoint to a 3000-series concentrator. Anyone have a config example of what I'm looking for?
