Firewall

[Mundo_digital]

Ola amigos;
to tendo momentos de lentidão na minha rede, tem horas q o ap chega a travar (quando olho no log tem la "critical router was rebooted"), o pessoal da suspeitando das minhas regras de firewall, abaixo tem todas as regras q tem em filter rules no meu servidor. quem puder ajudar eu agradeço:

pronto, vale lembrar que apesar de ter regra pra clientes nao se enchergarem, e a opcao ta marcada no cartao, os clientes continuam se enchergando

Aguardo a ajuda de vcs com ansiedade.

Amigo, analisando o seu problema, vc criou duas regras para a mesma coisa emuito mais trabalhoso, me procure que passo um conjunto de regras simples e extremamente eficiente.

[parreira13]

amigo, não será que o seu link está com cargalo, poste mais a respeito de seus link quantidade de clientes.
