To compound the situation, we get a maximum of 28.8 Kbps, because our modem-bank capabilities are limited. Needless to say, a VPN has the potential to upgrade this connectivity and save the company some cash. The home users will likely connect with cable modems to local ISPs, then use a VPN for secure access to the central office. Role No. 2 for a VPN within my company is to connect client LANs to our support groups in the main office. Much of our support is handled through secure dial-ups.
Clients phone our support people, who in turn dial into their system and work with the clients.
In this case, a VPN would let us leverage our connection to the Internet and form a private extranet between our customers and us. A VPN would serve to keep intruders out of internal and client systems. The connectivity issues raised were numerous and the answers not easy to determine. The amount and source of bandwidth into the company became a major topic of discussion as my research progressed. The questions began to pile up.
