Introduction
All TruView appliances have a firewall enabled for security. This firewall daemon is part of the CentOS 7 operating system. The default listening ports for flow exports that are open on the firewall are udp/2055-2555, udp/6343, tcp/6343 and udp/9995-9996.
When other listener ports are required, the firewall configuration needs modification.
Solution
- Connect to the applicance's CLI (SSH) and login
- Assume root priviledges by issuing the following command:
# sudo su -
- Verify the firewall's current configuation:
# firewall-cmd --zone=public --list-ports
- Add temporary as well as permanent policies to the firewall. In this example, we're adding port 2060 as a listning port:
# firewall-cmd --zone=public --add-port=2060/udp # firewall-cmd --zone=public --add-port=2060/udp --permanent
- Don't forget to add these listerner ports to the legacy TVF user interace as well.
