We are using SDN across 3 hosts with multiple VLANs configured all using OVS with a trunk port to an external firewall. Inter-VLAN traffic is routed and filtered by the external firewall (Unifi UDM Pro) and is working as expected. Now we would like to route all INTRA-vlan traffic to the external firewall as well, but I cannot seem to get it working. I enabled "Isolate Ports" on the VNET configuration and in the external firewall, I am allowing traffic within the same VLAN, but the clients still cannot ping each other. Can anyone please help?
