      Seguinte… acabei de refazer os testes e só funcionou quando eu deixei a instância padrão (configurada via webgui) como transparente e a segunda instância como autenticada. Segue os arquivos de configuração de cada.

      Instancia padrão squid.conf e transparente. (Deve ser configurada no webgi)

      Script de inicialização da segunda instância. (iniciará no boot)
      Pf 2.3: /usr/local/etc/rc.d/check_squid-auth.sh

      
      #!/bin/sh
      
      /bin/ps ax | /usr/bin/grep /usr/local/etc/squid/squid-auth.conf | /usr/bin/grep -v grep
      if [ $? -eq 0 ];then
          /bin/echo ok
      else
          /usr/local/sbin/squid -f /usr/local/etc/squid/squid-auth.conf
      fi
      
      

      Dessa forma ai eu consegui fazer funcionar.

        No meu caso preciso usar uma instancia como transparente para rede wifi com captive portal ( autenticacao e vouchers)
        E a outra instancia proxy ativo para rede dos funcionários.
        Preciso pegar os logs de acesso das duas redes.
        Você testou se esta pegando os logs de acesso das duas redes?

          Pra integrar o captive ao squid vc tem q trocar o script check_ip.sh pq o original tem bug. Depois posto o script q funciona aqui ,mas se quiser adiantar da uma pesquisada aqui no fórum em português… tem um colega q postou um  script q funciona.

                Sim.. os logs do webgui são das duas instâncias pq elas compartilham o cache.log e o access.log.

                    Poderia enviar o script do captive portal funcionando? Eu até testei o captive portal no 2.3.1 e parece que está ok nos meus testes, mas não coloquei em um ambiente de produção.
                    Você ativou o wpad na rede do proxy autenticado?
                    Já testei vários tutoriais sem sucesso, se puder enviar, agradeço.

                      O captive portal funciona ta normal sim. O problema é quando você muda a autenticação do squid para "captive portal". Além de nao  navegar, não loga os acessos dos usuários. Pra corrigir isso troque o conteúdo do script /usr/local/bin/check_ip.php por esse abaixo:

                      Obs: após a troca do conteúdo edite as configurações do squid e do captive portal e mande salvar (não precisa modificar)

                        Já tentaram no lugar de dois squid rodando, apenas um com custom acls?

                          Não tentei. Confesso que nao manjo muito dessas ACLs do squid, mas cheguei a pensar nisso. Na verdade seria uma opção mais elegante. :D

                            Além de elegante, fica tudo no backup e não precisaria de patches ou arquivos criados na mão.

                              Marcello já tentei fazer isso, mas do jeito que fiz não consegui criar as entradas no firewall pf que seria responsável por redirecionar a porta 80 para 3128 pois quando seleciona as interfaces e digo que são transparentes ele cria automaticamente duas entradas no firewall pf uma pass e uma rdr essas eu não consegui reproduzir na interface web que dica vc nos dá

                                    Não consegui rodar o squid em duas instancias…
                                    Configurei para cada interface o que eu queria, copiei o squid.conf das duas...
                                    mas acho que tem algo errado no script que peguei aqui...
                                    Meu cenário sao duas WANS, uma LAN (rede com proxy ativo) e LANWIFI(rede com proxy transparente).

                                    Esse script abaixo é pra rodar a outra configuração de proxy do squid

                                    
                                    Script de inicialização da segunda instância. (iniciará no boot) 
                                    Pf 2.3: /usr/local/etc/rc.d/check_squid-auth.sh
                                    
                                    #!/bin/sh
                                    
                                    /bin/ps ax | /usr/bin/grep /usr/local/etc/squid/squid-auth.conf | /usr/bin/grep -v grep
                                    if [ $? -eq 0 ];then
                                        /bin/echo ok
                                    else
                                        /usr/local/sbin/squid -f /usr/local/etc/squid/squid-auth.conf
                                    fi
