Do you want to create firewall rules on a T1 or a T0 router? Have you looked at Add or Delete a Firewall Rule to a Logical Router ?
No, I want to create firewall rules on an edge that is a fabric node, not a logical router.
I NSX-V it was possible, is it possible in NSX-T also?
NSX-V architecture is different and it is usually better if you don't try to think NSX-T in the way V was. In V the Edge is a router-VM and on T it is a VM that can host one or more logical routers. So it makes no sense having a firewall on the Edge itself if the router is an entity hosted inside it. What are you trying to accomplish?
OK, Thank you for the response.
