Hi there,
I have serious trouble configuring a LTSP-server, wanting it to
work as a transparent proxy using squid in order to secure
web-access for our children.
The problem is to redirect TCP-requests to the machine itself.
More detailed: I want the tcp-requests from users logged into
the LTSP-machine being redirected to the machines' proxy.
As mentioned above the proxy is running on the same system.
A simple
iptables -t -nat -A OUTPUT -m owner ! --owner-uid squid -p tcp
--dport 80 -j REDIRECT --to-destination 3128
doesn't seem to work, cause a browser would not be expecting a
reply from a transparent proxy when waiting for replies to its requests.
What am I doing wrong here? Do the packets have to masked
locally before redirecting them to the proxy?
Any help is appreciated as I have been guessing on this problem
for three days.
Regards,
Sascha
