What is security appliance address management?
In security appliance address management we have to configure IP addresses that connect a client with a resource on the private network, through the tunnel, and let the client function as if it were directly connected to the private network. Furthermore, we are dealing only with the private IP addresses that get assigned to clients. The IP addresses assigned to other resources on your private network are part of your network administration responsibilities, not part of VPN management. Therefore, when IP addresses are discussed here, we mean those IP addresses available in your private network addressing scheme that let the client function as a tunnel endpoint.
Does Cisco ASA verify AAA?

What is Cisco client policy?
The Cisco Client policy has end-users fetch their address from a DHCP server which doles out a specific subnet. Wanting to stick to that subnet, because there are nat-exempt and hairpin-nat rules already in place for it, that forward the clients on to other sites.
What happens if I take the DHCP server out of the tunnel group?
If I take the dhcp-server out of the tunnel-group and use an arbitrary ip local pool instead, the L2TP client adds the routes as per the split-tunnel-network-list ACL, but then won't pass the traffic because the nat-exempt and hairpin-nat does not match the ip local pool range.
