How to config Netflow version 11.11.2 My firebox xtm 800.
The netflow documentation here:https://www.watchguard.com/help/docs/help-center/en-US/Content/en-US/Fireware/basicadmin/netflow_configure.html
states that you need to be running 12.3 or better.
Any of the XTM 800 devices will be running 12.1.3 or 12.1.4 depending on the generation of the appliance.
In order to use netflow, you'll need a newer firewall that can run version 12.3 or better. If you are using a 810, 820, or 830 I would suggest upgrading to a firewall that is currently supported so that it will get software updates and bugfixes.
