# Never matches and should not be used outside the ssl_bump context.
#
# At each SslBump step, Squid evaluates ssl_bump directives to find
# the next bumping action (e.g., peek or splice). Valid SslBump step
# values and the corresponding ssl_bump evaluation moments are:
# SslBump1: After getting TCP-level and HTTP CONNECT info.
# SslBump2: After getting TLS Client Hello info.
# SslBump3: After getting TLS Server Hello info.
# These ACLs exist even when 'SSL/MITM Mode' is set to 'Custom' so that
# they can be used there for custom configuration.

–----------------UPDATE----------------------
No Proxy Server: General Settings/General, estava desmarcado a opção "Allow Users on Interface" e na ACL's em Allowed Subnets estava vazio. Foi marcar e funcionou a navegação controlada pelo Squid.
Fiz as alterações no squidguard, cliquei em aplicar e ao tentar acessar a página https://www.terra.com.br/ dá a mensagem SSL_ERROR_BAD_CERT_DOMAIN.
Obs. Já desinstalei a CA e instalei novamente na máquina que estou realizando testes.
