Opa Renato...
funcionou bacana agora!!!
so acrescentei no altq on { fxp0 fxp1 } , como ja tinha as regras de
saida pra interfaces, ele ja funcionou
meu problema agora q o acesso do server ficou limitado também...
tentei colocar
pass quick from any to $me (meu server)
pass quick from $me to any
mas ele ainda continua limitando...pelo q entendi, se eu coloco colocar
uma regra e nao especificar nenhuma queue ele vai passar livre, por fora
do altq...
eh assim mesmo? caso nao seja, como faco pra ignorar o altq para certas
regras? tem alguns ips que preciso deixar liberado...
Obrigado
