I set the security policy named LAMP as shown in the figure, and set it to monitor mode.
LAMP-DB | CentOS 7 MySQL is running on port 3306. LAMP-WEB database request is accepted. There is no control by fiwewalld. Can VMs in this tier talk to each other ? - No |
LAMP-WEB | CentOS 7 Wordpress and apache are running. Web services are launched on http port. There is no database, no control by fiwewalld. Can VMs in this tier talk to each other ? - No |
Then I did the following:
- View LAMP-WEB in browser from 192.168.0.0/23 segment.
- Ping to LAMP-DB from 192.168.0.0/23 segment.
However, “Monitoring” screen shows “Tcp Port:80 No flows found” (as shown in the figure) and despite success of the ping, “No uncaptured traffic flows were detected." is displayed.
Why can't "Monitoring" catch the packets?
