About IPsec Tunnels
IPsec stands for IP Security, a set of protocols that suppor ts secure exchange of IP packets at the IP layer.
IPsec is deployed widely to implement Vir tual Private Networks (VPNs). See
for more
information.
IPsec suppor ts two encr yption modes: Transpor t and Tunnel. Transpor t mode encr ypts only the data por tion
(payload) of each packet, but leaves the header untouched. The more secure Tunnel mode encr ypts both the
header and the payload. On the receiving side, an IPsec-compliant device decr ypts each packet. Netopia
Routers suppor t the more secure Tunnel mode.
DES stands for Data Encr yption Standard, a popular symmetric-key encr yption method. DES uses a 56-bit key.
The Netopia 4541/4542 offers IPsec DES encr yption over the VPN tunnel.
