      Boa tarde.

      Hoje cheguei na empresa e minha internet estava da seguinte forma:

      – Conseguia baixar emails sem problemas

      – Skype Conectava normalmente

      Mas não estava conseguindo acessar nenhuma pagina de internet: http://www.google.com.br, http://www.uol.com.br, http://www.yahoo.com.br não conseguia entrar em absolutamente nenhuma pagina de internet.

      Reiniciei o PC e nada, Reiniciei o modem da telefonica e nada, Reiniciei o Endian e nada! Simplesmente não consigo acessar paginas na internet.

      Depois de fuçar muito no Endian fiz o seguinte teste:

      Meu proxy estava configurado como transparente e tentei colocar como Não Transparente.

      Como não transparente a internet voltou porém minha black list não está sendo aplicada. Esta sendo possível visitar qualquer site.

      Como transparente não vai e como Não Transparente acessa mas acessa sem respeitar minha black list.

      Esse problema ocorreu do nada. Ontem quando eu fui embora estava tudo normal e hoje quando eu cheguei enctontrei esse problema.

      Uso o Endian 2.4 alguem sabe me dizer o que pode estar ocorrendo?

      Segue log:
