Squid content filtering rule

[welliott]

I am trying to block avi, mp3, mpeg, mpg and exe files automatically and am using it in conjunction with Snort. What I want to do however is to be able to allow specific IPs to be excluded from this rule.

The Squid acl is simply this;

.[Ee][Xx][Ee]
.[Aa][Vv][Ii]

… and so on.

I have tried adding various allow src statements with the IP address specfied to it but it still blocks everything. Can someone tell me how to get around this?

thanks.
