Abstract
Some embodiments provide a method that receives a packet, having a set of one or more layer 7 (L7) expressions, from a datapath. The method identifies a set of datapath firewall rules that match on expressions in the set of expressions. The method provides identifiers for the datapath firewall rules of the identified set to the datapath. The datapath uses the identifiers and additional packet header data to determine a matching firewall rule from the set of datapath firewall rules.
