SafeHarbour IPSec Settings
SafeHarbour VPN is a tunnel between the local network and another geographically dispersed network
that is interconnected over the Internet. This VPN tunnel provides a secure, cost-effective alternative to
dedicated leased lines. Internet Protocol Security (IPsec) is a series of ser vices including encr yption,
authentication, integrity, and replay protection. Internet Key Exchange (IKE) is the key management pro-
tocol of IPsec that establishes keys for encr yption and decr yption. Because this VPN software imple-
mentation is built to these standards, the other side of the tunnel can be either another Motorola
Netopia
®
unit or another IPsec/IKE based security product. For VPN you can choose to have traffic
authenticated, encr ypted, or both.
When connecting the Motorola Netopia
®
unit in a telecommuting scenario, the corporate VPN settings
will dictate the settings to be used in the Motorola Netopia
®
unit. If a parameter has not been specified
from the other end of the tunnel, choose the default unless you fully understand the ramifications of
your parameter choice.
