I dont think i would be the only one looking in to this.
We have a wireless network and are looking for a solution to block / filter and scan all traffic comming though the network before it ends up at users.
When we use to use ISA server GFI done a product which would do that.
I am running ububtu with Squid 2.6.18 Stable
Can anyone help me out with more info. Email me at: darren(at)rednetwifi.com
