Hi Folks,
I have installed squid 3.0 stable 1 and have configured it for
transparent mode.
Somehow it doesn't seem to work correctly.
When it runs, it shows that it is running in transparent mode, but then
when HTTP requests hit the box it gives the WARNING: Transparent
proxying not supported. The web browser shows an error page but from the
squid itself (Error: HTTP 400 Bad Request - Invalid URL.....).
When I configured the build, I used the tproxy and the netfilter options
for transparent proxying as I wasn't sure what one I needed.
Does anyone have a clue why it will not run in transparent mode.
I am pretty sure my iptables is OK
Here is what the trace shows:
