squid: msn nao acessa
Galera, estou com um problema e gostaria muito da ajuda de vocês pra resolver esse problema. Instalei o Debian 31. R5, nele tenho um firewall e um proxy rodando, só que é ai que está o problema. O meu proxy é transparente, porem, acesso todos os sites, mas não consigo acessar o email do homail e nem o messenger. Mesmo com ele transparente, se eu for nas opções de Internet/configirações de lan e colocar o ip e a porta continuo acessando todos os sites, so que dessa maneira acesso o email do hotmail, mas não acesso o messenger. Galer ajuda ai que meu chefe já ta com a faca na minha garganta. Agradeço desde já

blz veio, obrigado pela atenção, vou postar na ordem o meu firewall e o meu squid.conf, ok? Só pra adiantar. Tenho um pc com o Debian Sarge 3.1 r5 instalado e esse firewall e squid.conf tão rodando nele, mas com esse problema que falei anteriormente.
