7. For Position, type a number.
The position determines the order in which the TMS zl Module processes
IPsec policies. The module processes the policy with the lowest value first
(for example, position 1 before position 2). The position matters most
when policies have overlapping traffic selectors. In this case, assign the
highest position (lowest value) to the IPsec policy with the most specific
traffic selector.
Note that you can specify a position that is already used by another policy.
The new policy is inserted above the former policy. You can use the arrow
icons in the Tools column in the VPN > IPsec > IPsec Policies window to
rearrange policies. Remember the policy at the top of the display is the
first policy processed.
A default IPsec policy prevents all traffic from being encrypted by the VPN
engine; therefore, all IPsec policies that you configure must have a higher
priority than this default policy.
Next, you configure the VPN traffic selector, which determines which traffic
is selected by the policy. For example, the selector might specify all IP traffic
between 192.168.2.0/24 (a local subnet) and 192.168.3.0/24 (a remote subnet).
For a policy with the Apply action, the selected traffic is the traffic that is sent,
received, and secured on the IPsec SA.
