In fact, we also need to pay attention to one thing, Because when a packet passes through a chain, All the rules of the current chain are matched, However, there must always be an order when matching. We should match one by one, and we said that rules of the same functional type will gather in a "table". Then, which rules in the "table" will be executed at the front of the "chain"?
