[squid-users] Squid Transparent Proxy with Coovachilli is not working

[sknz]

So I was testing from a client device(10.1.0.2) which is connected over WiFi
to an AP and that AP is connected to eth1 physically. In case you're
wondering, eth1 is connected to the server physically. Trying to connect an
HTTP website from the above-mentioned client device...

================

So in eth1, we received the request from the client.

So tun0 also received it from eth1. Now, tun0 is supposed to send it to
eth0(WAN)...

================

https://paste.grasehotspot.org/view/raw/0b69d9db

But we don't receive anything at all in eth0(WAN)... Now let's see what
we've got back from tun0/eth1 to client device.

================

https://paste.grasehotspot.org/view/raw/9ad866a5

tun0 is passing back the acknowledgment to eth1 and eth1 is also doing same
to client device... and it stops here. So no actual data!

================

I guess from here tun0 is supposed to send it to squid and squid is suppose
to send it to eth0(WAN). Correct me if I'm wrong. I have got a Perl script
which shows TOP like interface for real-time packets. So the moment client
device tries to connect to HTTP, port 3127 gets GREEN which means something
sent/received. But it never gets green for forward-proxy port 3128.
