About IPsec Tunnels
IPsec stands for IP Security, a set of protocols that supports secure exchange of IP packets at the IP layer.
IPsec is deployed widely to implement Virtual Private Networks (VPNs). See
information.
IPsec supports two encryption modes: Transport and Tunnel. Transport mode encrypts only the data portion
(payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encrypts both the
header and the payload. On the receiving side, an IPsec-compliant device decrypts each packet. Netopia
Routers support the more secure Tunnel mode.
DES stands for Data Encryption Standard, a popular symmetric-key encryption method. DES uses a 56-bit key.
The Netopia 4741 offers IPsec DES encryption over the VPN tunnel.
Configuration
IPsec tunnels are defined in the same manner as PPTP tunnels. You configure the Connection Profile as follows.
From the Main Menu navigate to WAN Configuration and then Add Connection Profile.
