IKE Phase 2 (IPsec SA)
IPsec SA Life
Time
This setting does not have to match the remote VPN end-
point; the shorter time will be used. Although measured in
seconds, it is common to use time periods of several hours,
such 28,800 seconds.
IPSec PFS
If enabled, PFS (Perfect Forward Security) enhances security
by changing the IPsec key at regular intervals, and ensuring
that each key has no relationship to the previous key. Thus,
breaking 1 key will not assist in breaking the next key.
AH Authentication
AH (Authentication Header) specifies the authentication
protocol for the VPN header, if used.
AH is often NOT used. If you do enable it, ensure the algo-
rithm selected matches the other VPN endpoint.
ESP Encryption
ESP (Encapsulating Security Payload) provides security for
the payload (data) sent through the VPN tunnel. Generally,
you will want to enable both ESP Encryption and ESP Authen-
tication.
Select the desired method, and ensure the remote VPN
endpoint uses the same method. The "3DES" algorithm
provides greater security than "DES", but is slower.
ESP Authentica-
tion
Generally, you should enable ESP Authentication. There is
little difference between the available algorithms. Just ensure
each endpoint use the same setting.
