We're trying to implement a dial vpn solution for some customers and i'd like to know
your recomendations:
1. Customer wants to use isdn in order to get connected (he will use our NAS's).
2. Customer wants to transmit data under tunneling/encryption when accessing his VPN (L2TP/IPSEC ?).
3. Customer wants to implement voice as well after a while.
Which would be the best way to implement the above?
Can we use cisco 803's from customer's side and a vpn concentrator from our side?
Can the above scenario be used for internet+voice access too?
