VPN
A VPN is a connection between two endpoints in different networks that allows
private data to be sent securely over a shared or public network, such as the
Internet. This tunnel establishes a private network that can send data securely by
using industry-standard encryption and authentication techniques to secure the
data sent.
Summary
This feature displays general information about the VPN tunnel settings. The
device supports up to 100 tunnels. The Virtual IP Range is reserved for EasyVPN
users or VPN clients that connect to this device with the Mode Configuration
option (described in
Advanced Settings for IKE with Preshared Key and IKE
with Certificate ) enabled.
To set a range of IP addresses to be used for VPN tunnels, click Edit and enter the
following parameters:
• Range Start and Range End —Starting and ending range of IP addresses
used for VPN tunnels.
• DNS Server 1 and DNS Server 2 —Optional IP address of a DNS server. If
you enter a second DNS server, the device uses the first DNS server to
respond. Specifying a DNS server can provide faster access than using a
DNS server that is dynamically assigned. Use the default setting of 0.0.0.0 to
use a dynamically assigned DNS server.
• WINS Server1 and WINS Server 2 —Optional IP address of a WINS server.
Windows Internet Naming Service resolves NetBIOS names to IP
addresses. If you do not know the IP address of the WINS server, use the
default, 0.0.0.0.
