I tried that on client pc (in isolan) and i didn't change anything.
> ping <dns server>
> ping www.google.com
Anyway, as I don't do any nat, I would expect not to ping it!
*******************
route (on pc in isolan) :
$route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.2.0 * 255.255.255.0 U 0 0 0 eth0

*****************
If I do a ping in isolan to dns server (192.168.0.1) :
$ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.

And the tcpdump (while pinging)

14:32:21.548084 arp who-has 192.168.0.1 tell 192.168.2.4
And I don't get any reply!?
I am a bit lost, does all dns request has to go through squid, or computers in my isolan have got to reach directly the dns server??
