Policy
Local Policy
Select the address corresponding to the local network. Use
Create
new Object
if you need to configure a new one.
Remote Policy
Select the address corresponding to the remote network. Use
Create
new Object
if you need to configure a new one.
Policy
Enforcement
Clear this to allow traffic with source and destination IP addresses
that do not match the local and remote policy to use the VPN tunnel.
Leave this cleared for free access between the local and remote
networks.
Note: Clear this to use the IPSec SA in a VPN concentrator.
Selecting this restricts who can use the VPN tunnel. The ZyWALL
drops traffic with source and destination IP addresses that do not
match the local and remote policy.
Phase 2 Settings
SA Life Time
Type the maximum number of seconds the IPSec SA can last. Shorter
life times provide better security. The ZyWALL automatically
negotiates a new IPSec SA before the current one expires, if there are
users who are accessing remote resources.
Active Protocol Select which protocol you want to use in the IPSec SA. Choices are:
AH
(RFC 2402) - provides integrity, authentication, sequence
integrity (replay resistance), and non-repudiation but not encryption.
If you select
AH
, you must select an
Authentication
algorithm.
ESP
(RFC 2406) - provides encryption and the same services offered
by
AH
, but its authentication is weaker. If you select
ESP
, you must
select an
Encryption
algorithm and
Authentication
algorithm.
Both
AH
and
ESP
increase processing requirements and latency
(delay).
The ZyWALL and remote IPSec router must use the same active
protocol.
Encapsulation
Select which type of encapsulation the IPSec SA uses. Choices are
Tunnel
- this mode encrypts the IP header information and the data.
Transport
- this mode only encrypts the data.
The ZyWALL and remote IPSec router must use the same
encapsulation.
