Hi,
when enabling dFW in an OrgVDC the dFW Section inside NSX is added at the first position.
Referencing to:
https://fojta.wordpress.com/2017/03/01/vcloud-director-8-20-distributed-firewall/
it was possible in 8.20 to append the new dFW section at the end of the dFW.
In vCD 9.7 and NSX 6.4.5 i receive a receive a "400 BAD REQUEST". Without "?append=true" the dFW Section is created fine.
Is the function broker or was removed?
