I am curious to know if anybody out there really uses ISP-driven mandatory VPDN's. By that, I don't mean the client-driven PPTP/L2TP tunnel for the roving salesmen to dial back into the office network, as I am well aware that this is quite popular. What I am talking about is the ISP-provided mandatory VPDN, where the access-server is the LAC , and there is a 3-tier architecture between client, LAC, and LNS. Now that IPsec, and accompanying client software is so prevalent, it seems to me that there is not much reason to use ISP VPDN's at all. I understand that there are certain advantages from a ISP VPDN that are unavailable from a client-driven VPN. But it seems to me, at first blush, that these advantages do not outweigh the added cost and frustration of dealing with a telco. So can anyone present a case when an ISP VPDN is indeed the best solution, better than any of the alternatives? Note - I'm not trying to dis' anybody who really likes ISP VPDN's. I Not at all. I am sure there must be some reasons for using them. I am just trying to gain an understanding of what those reasons might be.
