New in FreeBSD 4.0, is the concept of stateful filtering. This is a big improvement for UDP traffic, which typically is a request going out, followed shortly thereafter by a response with the same set of IP addresses and port numbers (but with source and destination reversed, of course). For firewalls that have no statekeeping, there is almost no way to deal with this sort of traffic as a single session. But with a firewall that can "remember" an outgoing UDP packet and, for the next few minutes, allow a response, handling UDP services is trivial. The following example shows how to do it. It is possible to do the same thing with TCP packets. This allows you to avoid some denial of service attacks and other nasty tricks, but it also typically makes your state table grow quickly in size.
O conceito de filtragem stateful é novo no FreeBSD 4.0. Esta é uma grande melhoria para o tráfego UDP, que geralmente é uma solicitação que sai, seguida logo depois por uma resposta com o mesmo conjunto de endereços IP e portas (mas com origem e destino invertidos, é claro). Para firewalls que não têm o controle de estado, quase não há como lidar com esse tipo de tráfego como uma sessão única. Mas com um firewall que pode "lembrar" de um pacote UDP de saída e, nos próximos minutos, permitir uma resposta, lidar com serviços UDP é trivial. O exemplo a seguir mostra como fazer isso. É possível fazer a mesma coisa com pacotes TCP. Isso permite evitar alguns ataques de negação de serviço e outros truques desagradáveis, mas também faz com que a tabela de estado cresça rapidamente em tamanho.
