Hey, There are couple missing pieces(in my eyes) in order to understand the picture. Is this squid box a router or just a proxy? What tcpdump command did you ran? What is the networks that are involved? What is the gateway and dhcp for this network? If the client is a linux box then we need the output of: $ ifconfig $ route -n Or $ ip route
