VPN Configuration
In addition to a full firewall functionality, the IP30 Tele, Satellite,
and Satellite Plus enable secure telecommuter access from home to
the office network through the virtual private network (VPN)
functionality.
A VPN consists of at least one VPN server or gateway, and several
VPN clients. A VPN server makes the corporate network remotely
available to authorized users, such as employees working from
home, who connect to the VPN server by using VPN clients. A
VPN gateway can be connected to another VPN gateway and
enable the two connected networks to function as a single network.
A connection between two VPN sites is called a VPN tunnel. VPN
tunnels encrypt and authenticate all traffic through them. Through
these tunnels, you can safely use your company’s network
resources when you work at home. For example, you can securely
read email, use your company intranet, or access your company
database from home.
IP30 Tele, IP30 Satellite and Satellite Plus provide VPN
functionality.
The IP30 Tele acts as a VPN client and can establish secure VPN
tunnels to your office VPN gateway.
IP30 Satellite and Satellite Plus can act as a VPN client, a VPN
server, or a VPN gateway.
