Bandlimit com cache

Galera esta brabo de encontrar informações sobre o meu problema. Possuo um link de Velox com 4 MBps, e fiz o compartilhamento com o pessoal do prédio onde moro, limitei a galera em 128Kbps para download e upload. Até ai tudo bem o compartilhamento esta funcionando bem, mais estes computadores que estão com limite de banda, não conseguem utilizar o cache do meu proxy, quando paro o meu bandlimit, eles conseguem ter acesso ao cache, e também ficam sem qualquer limite de banda. Se alguém puder me ajudar ficarei muito grato.....

Galera mais uma vez venho pedir a ajuda de vocês, pois continuo com o "problema" de não conseguir ter acesso ao cache do squid com a utilização do Bandlimit, ou seja a rede que esta com limite vai direto para a internet e utiliza o cache, mais quando paro o Bandlimit, essa rede acessa normalmente o cache. Segue abaixo os meus scripts e arquivos de configuração do Squid, Firewall e Bandlimit. Ficarei muito grato caso alguém possa me ajudar. (Devido ao limite de caracteres abaixo segue só o do squid na outra mensagem segue o Firewall e o Bandlimit)

#ChangeLog v0.4
# Descobre o path dos binários usando which (by Eri Ramos Bastos erirb at xtms.com.br)
# transforma stop e start em funções (by Eri Ramos Bastos erirb at xtms.com.br)
# cria uma função de instalação (by Eri Ramos Bastos erirb at xtms.com.br)
# cria um menu "init-like" (start|stop|restart|install) (by Eri Ramos Bastos erirb at xtms.com.br)
# verifica sempre se o sistema está instalado antes de executá-lo (by Eri Ramos Bastos erirb at xtms.com.br)
# permite maior modularização (by Eri Ramos Bastos erirb at xtms.com.br)
# resolvido problema de nao utilizacao do modulo de compartilhamento


#ChangeLog v0.3
#adicionado compartilhamento de Link

#ChangeLog v0.2
#
#Adicionado opcao para PATH de executaveis


# Dependencias
# Ipchains ou Iptables , iproute2 , modulos do kernel de CBQ QoS e compania... hehehe :)
# Iptables: necessita de iptable_mangle e ipt_MARK
# Ipchains: nenhuma

##################
#INSTALACAO
# crie o diretorio bandlimit dentro do seu /etc
##mkdir /etc/bandlimit
# dentro deste diretorio crie os arquivos ips e interfaces
##touch /etc/bandlimit/ips
##touch /etc/bandlimit/interfaces
# depois edite o ips e o interfaces
# colocando dentro do ips
# os ips que vc deseja limitar 1 por linha no seguinte formato
# ip:ratein:rateout ex: 10.0.1.2:97:33
# e no interfaces as interfaces que vc usa na sua maquina
# no formato ethx ex: eth0
# 1 por linha tambem :)))
#
# Para rodar coloque o script dentro do seu rc.local
# Para remover as regras digite rc.bandlimit stop

#Lembrando que usamos o mangle apartir do mark 2 e este vai gerando um mark novo
