Sure, you have always had SmartView Monitor dashboard to see real-time statistics, but you need a separate license for that.
Finally, starting with R76 for regular firewall and R75.40VS for virtual one we have Netflow export capability available in Gaia OS. It supports Netflow version 5 and 9. I haven't tried version 9 but all common version 5 works as expected. Features and limitations:
- SecureXL (i.e. hardware acceleration) should be enabled for correct results (most of today's firewalls have it on anyway).
- You can set up to 3 external collectors to receive Netflow data. Of course it means that the same Netflow packet will be sent 3 times, I don't see reason to do so.
- You can specify source IP address for outgoing Netflow packets, the defult is IP of the interface where packets leave.
- Do not forget to set Netflow version, as default is 9.
