I removed a P2P circuit to bring in more bandwidth to a remote office. In the process, my 1700s are being replaced by 2400 series IADs. Is it possible to configure each to work with the other? I mean static routing tables to one another, or a site to site VPN technology I can employ to seemlessly connect clients to my MDF remotely and authenticate against Active Directory? Thanks in advance and sorry to be bumbling about the question, but I am pressed for time.
