I have a L2L tunnel setup with one of our customers which we do development work for. We have hired some external consultants that need to work on servers that are located at the customers site. I am curious if it's possible for the consultants to login to our network via a VPN client and then access the L2L tunnel. I have never tried this before and the customer is telling me that this will work. We are using a 3020 concentrator if that makes a difference. If it's possible can someone explain the process to make this work.
