Table B-2. VPN Configuration Parameters
Parameter Description Values
VPN Name A name to identify the VPN. This name does not
need to match the name at the distant location, but
this is recommended for continuity
Max 15 alphanumeric
characters
Dest. IP address The IP address of the remote device. 0.0.0.0 -
255.255.255.255
(4 bytes)
Default = 0.0.0.0
IKE Encryption Type of Internet Key Exchange encryption to be
used. Null is implemented as described in
RFC2401. DES is implemented as described in
RFC2405. 3DES, or Triple DES, is described in
ANSI X9.52-1998.
Null (default)
DES
3DES
IKE Hash The method used to guarantee the integrity of your
data. MD5 is defined in RFC1321. SHA-1 is
described in FIPS180-1.
MD5 (default)
SHA-1
IKE Lifetime Sets the lifetime of an IKE security Association
(SA). Set to zero for unlimited, or in full day
increments up to 9999 days. If the initiator and
responder Lifetime values are not the same, the
shortest duration will be adopted at both ends.
0 (= unlimited)
1- 9999 days
0 (default)
IKE Setup Main is a 6-step (3 round trip) process that provides
identity protection by encrypting the identities of the
peers. Aggressive mode is somewhat faster than
Main, but it does not protect the identities of the
communicating parties.
Main (default)
Aggressive (not
currently supported)
Key Exchange Manner in which keys are exchanged. Private (default)
Public (not currently
supported)
Private Key1 The key to exchange when Private is selected
above. It is required when Private is selected.
Max 16 hexadecimal
characters
Diffie-Hellman This is a means for two parties to agree upon a
shared secret in such a way that the secret is
unavailable to eavesdroppers. The secret can then
be converted into cryptographic keying material for
other algorithms. The length of the key could cause
slower connection setup.
768 (default), 1024, or
1536 bit.
Encapsulation Type of encapsulation used. Only tunnel mode is
available at this time.
