Our Cisco engineer told me so. First he closed all ports and opened only
incoming 3130/udp, 3128/tcp, 4827/tcp and no restrictions for outgoing ports.
After that I stoped to receive any ICP requests but not HTTP. So I had to
ask him to open all udps and tcps above 1024 for outgoing and incoming,
then all started to work again.
