		Bom dia pessoal, sou novo aqui, 
sou novo em Linux também,
acabei assumindo algumas coisas que um terceiro cuidava e sou bem novato na parte de squid, linux etc, comecei um curso porém o conhecimento estou pegando na pratica mesmo.
me bati bastante mas não encontrei a solução,
temos uma vpn CISCO que está tudo certo, acessa toda a rede, porém os ips dos DVR para acesso as câmeras não acontece nada, vi que poderia ser um problema no proxy ou portas dos dvrs,
lendo alguns tópicos aqui, rodei alguns comandos porém não consigo achar algo de errado,

estes ips 172.16.1.236/237 e 238 são os ips dos DVRs, alguém consegue me dar uma luz?
