address type:
IP Subnet, to protect the whole subnet.

Identity Type
Select the identity type to identify this cable modem by:
WAN IP (remote endpoint) address

Email address
In Aggressive mode, the VPN concentrator identifies incoming SAs
by ID type and content, since this identifying information is not
encrypted, to distinguish between multiple rules for SAs that connect
from remote IPSec routers that have dynamic WAN IP addresses.
In Main mode, the ID type and content are encrypted to provide
identity protection. In this case VPN concentrator can only
distinguish between up to 30 different incoming SAs that connect
from remote IPSec routers that have dynamic WAN IP addresses.
Because you can select between five encryption algorithms (DES,
3DES, AES-128, AES-192 and AES-256), two authentication
algorithms (MD5 and SHA1) and three key groups (DH1 and DH2,
DH5) when you configure a VPN rule. The ID type and content act
as an extra level of identification for incoming SAs.
