Blocking Squid Requests

Blocking Squid Requests

[Walter Priesnitz Filho]

Hi,
I have this environment, a subnetwork (192.168.0.0) that access another
subnetwork (192.168.59.0) and then access the internet. The second lan has a
proxy server (squid:3128).
I need to block the requests in th first lan to the squid server to some
sites. How can I do this?
I've tried this
iptables  -A FORWARD -p tcp -m multiport --dport 80,443,3128 -d
www.someplace.com -j DROP
but doesn't work.
Can anybody help-me?

Regards,
      Walter

why don't use OUTPUT/INPUT  chain? 
you disable output/input from the lan to your firewall (so squid doesn't get 
requests)

Why not use squidGuard? Or even squid a squid acl?

Hi,

 It is better to add the acls on the squid than on the firewall. Proxy
servers will give good performance compared to the firewalls in acls.
