Configure Global IPsec Settings
Follow these steps to configure global IPsec settings:
1. In the Web browser interface left navigation bar, click VPN > IPsec.
2. Click the Settings tab.
3. By default, the Enable IPsec VPN check box is selected:
• Clear the check box to disable IPsec VPN functionality on the entire
TMS zl Module.
When this setting is disabled, the module will not act as a VPN
gateway, initiate VPN tunnels, nor respond to IKE and IPsec messages
from remote endpoints. The module will forward IKE and IPsec traffic
to endpoints behind it if you have created access policies that allow
such traffic.
• Select the check box to reenable the IPsec VPN functionality.
Your IKE, IPsec, and L2TP policies can now take affect.

4. Configure how the TMS zl Module handles ICMP error messages:
• Select the Send ICMP error messages check box to have the TMS zl
Module return an ICMP error message when it receives bad data.
By default, this check box is selected.
