By the help of God. Hi All, I'm trying to configure squid as a transparent proxy using TPROXY. The machine I'm using has 2 NICs, one for input and the other one for output traffic. The TPROXY iptables rules are configured on the input NIC. It looks like iptables TPROXY redirect works but squid prints out the following error: ERROR: NAT/TPROXY lookup failed to locate original IPs on local=xxx:443 remote=xxx:49471 FD 14 flags=17 I think I loaded all TPROXY required kernel modules. The ip forwarding works fine without the iptables rules. and I don't see any squid ERROR on getsockopt Please let me know what I'm missing?
