Troubleshooting the TMS zl Module in Routing Mode
■ What happens if the TMS zl Module does not match traffic to a NAT
policy?
The TMS zl Module will continue to process the traffic if there are no NAT
policy matches. The module will try to match the traffic against access
policies, and if the traffic matches an access policy, it will not be dropped.
Troubleshooting Port Maps
You receive one of the following errors when you try to add a port map:
■ At the CLI:
Error failed to add port-map
■ At the Web browser interface:
The port map could not be added.
Make sure that the number of port map entries does not exceed the limit. The
TMS zl Module currently supports up to 1001 port map entries.
Troubleshooting IPS
If you need to troubleshoot IPS, you should first check the following:
■ IPS is enabled globally.
■ IPS is enabled on each access policy for which you want to check the
related traffic.
Ensure That IPS Is Enabled Globally
To check the global IPS setting, complete the following steps:
1. Click Intrusion Prevention > Settings.
2. Click Actions.
3. Ensure that the Enable Signatures and Protocol Anomaly detection option is
selected.
