"First, a packet is checked against the port firewall filter, if present. If the packet is permitted, it is then checked against the VLAN firewall filter, if present. If the packet is permitted, it is then checked against the router firewall filter, if present. The packet must be permitted by the router firewall filter before it is processed." https://www.juniper.net/documentation/us/en/software/junos/routing-policy/topics/concept/firewall-filter-ex-series-understanding.html
