Isso significa que o TinyProxy está funcionando. Olhe mais para baixo para encontrar a configuração ACL para tinyproxy. Você precisa dizer quais intervalos de IP devem ser aceitos. Na documentação :
Allow
Deny
The Allow and Deny options provide a means to customize which clients are
allowed to access Tinyproxy. Allow and Deny lines can be specified multiple
times to build the access control list for Tinyproxy. The order in the config
file is important. If there are no Access or Deny lines, then all clients are
allowed. Otherwise, the default action is to deny access. The argument to
Access or Deny can be a single IP address of a client host, like 127.0.0.1,
an IP address range, like 192.168.0.1/24 or a string that will be matched
against the end of the client host name, i.e, this can be a full host name like
host.example.com or a domain name like .example.com or even a top level domain
name like .com.
