Regras de segurança no mk

[paulosjbv]

Boa noite
sou iniciante em mk e tenho um pequeno provedor com mk, eu uso pppoe e hotspot para fazer autenticaçao dos clientes.
Gostaria de saber de voçes que tem muita experiencia o que devo fazer e quais regras usar para manter a segurança no provedor.
-Tenho que colocar alguma regra de bloqueio de port scan ou virus ?

Paulo é sempre bom você ter essas regras para que venha se proteger de eventuais problemas.
Da uma pesquisada aqui no forum que você acha o pessoal postando varias regras de firewall ai é só você ir testando e adaptando para sua rede.

[paulosjbv]

entao
achei varias mas gostaria de saber quais devo usar.
ex: eu na minha opiniao nao devemos colocar regras de bloqueio de virus no router pois pode deixa-lo lento ou mesmo barrrar algum serviço basico, mas tem gente usando será que estou errado?
uma regra que achei interessante foi a de bloquear port scan até coloquei aqui mas fui testar um por scan na minha maquina e vi que nao bloqueou entao gostaria de saber quais sao e se as regras funcionan mesmo.

[paulosjbv]

o que acham de fazermos uma lista com regras basicas de segurança onde protegesse o router e todos pudeseem usar ? isso é possivel ?

[leoservice]

Ai vai algumas para voce ver

http://wiki.mikrotik.com/wiki/DoS_attack_protection

http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/Filter Neste link veja sobre Router Protection

as regras de virus que voce achar na net tem que ter cuidado pois pode estar barrando portas de serviços que voce ou seu cliente precise.

Bom, vamos tentar melhorar bem essas regras que vou postar.
