squid crashing

i think you may check size of partation where your log files are stored. Acess.log,store.log some time lack of space cause to responding squid.

df -l

To be honest, using a transparent proxy like squid or dansguardian is definitely the easiest way to do this. But you can kind of hack together a solution using iptables and restricting which IP addresses an internal system can connect to. Could you be a bit more specific about what you are trying to do, like limit browsing to a handfull of sites? Restrict only a handfull of sites? Block content by keyword? Are the users browsing from the Whitebox machine or are they on internal machines using the Whitebox system as a firewall/gateway?

what shorewall does not do

Just want to add that Shorewall, great as it is, will not do any of this. Cut and paste from

Shorewall Does not:

Act as a “Personal Firewall” that allows internet access by application.

Work with an Operating System other than Linux (version >= 2.4.0)

Act as a Proxy (although it can be used with a separate proxy such as Squid or Socks).

Do content filtering:

HTTP - better to use Squid and Dansguardian for that.

Email -- Install something like Postfix on your firewall and integrate it with SpamAssassin , Amavisd-new and Clamav

Configure/manage Network Devices (your Distribution includes tools for that).

I am fiddling with something similar as hariiyer as an add-in on my current gateway (which is basically shorewall)
and it seems squid will do the job......
