traffic-selector
With this command, you configure the VPN traffic selector, which determines
the traffic to which this policy is applied. For example, the selector might
specify all IP traffic between 192.168.2.0/24 (a local network) and 192.168.3.0/
24 (a remote network). For a policy with the Apply action, the selected traffic
is the traffic that is sent and received (and secured) on the IPsec SA.
Caution If your traffic selector will include management traffic to the TMS zl Module
itself, you first must configure a Bypass policy with top priority that selects
the management traffic, or you will be locked out of the Web browser inter-
face. If you do lock yourself out, reboot the module, but DO NOT SAVE the
configuration.
Similarly, the traffic selector must not include the local gateway address
(configured in the IKE policy) unless the selector is limited to specific proto-
cols such as UDP L2TP. If, however, for whatever reason the local addresses
include the local gateway address, you must create a Bypass policy to exclude
IKE traffic to and from the module from the VPN. Otherwise the VPN cannot
be established.
If your traffic selector will include traffic that is also selected for NAT, you
must create a NAT exclusion policy. See “Exclusion NAT Policies” in
Chapter 5: “Network Address Translation.”
