Bem tenho e redes em meu provedor, todas passando pelo squid. Duas inválidas e uma válida. O que acontece é o seguinte, elas saem pela eth1 ou eth2. 10.0.0.0/24, 192.168.0.0/24 e 200.222.x.xxx/25. Acontece que deixei o squid ativo e removi do arquivo de firewall a regra que redireciona da porta 80 para a 3128. Acontece que o /var/log/squid/access.log gerou um arquivo com esse conteúdo apenas:

Estou sendo invádido? O que fazer para resolver? Tem outra coisa, quando altero a porta que o proxy squid fica escutando, ele funciona perfeito por uns dias e depois pronto, faz isso novamente, ips estranhos no access.log.
