Minimum Symmetrical Rate: From the drop-down list, choose the
minimum data rate that you are prepared to accept for your

256 Kb. This rate must be lower than the Desired Symmetrical
Rate. If the connection cannot meet this requirement, an
error message displays.
Virtual Private Network: A Virtual Private Network (VPN) enables
remote offices or users to gain secure access their organization's
network over the public telecommunications network. This
provides the benefits of remote access without the expense of
dedicated leased or owned lines. VPNs work by using tunneling
protocols, such as L2TP, to encrypt data at the sending end, and
decrypt the data at the receiving end. This "tunnel" cannot be
accessed by data that is not properly encrypted.
