Hi,
--
I've configured a transparent squid proxy on a centos 6.6 with single NIC.
There is Cisco ISG in between with L4 redirection on www traffic.
The requests are coming on port 80 from client and ISG forwards that to port 80 on my squid server.
So there is no iptables configured on squid server.
Client requests are not reaching upto my squid instance.
I'm getting the following in pcap on squid box.
