Internet Filter

Hi -
I am looking for a purely internet-based web/content filter.  I currently use opendns, which works well from a technical point of view.  However, their categories are horribly inaccurate.  Any ideas for an alternative?  I do not mind paying; however, this is for my home, so I do not want to spend too much.

Thanks,

I guess I need to understand more about what exactly you need - but have you thought about using a browser extension as a web content filter?

The WOT (Web of Trust) extension is pretty solid and performing content filtering and has plug ins for all the major browsers.

k9 is free for home use and is offered for one computer (windows or mac software available).

To get more licenses (to be used at home) you have to follow this advice: http://www1.k9webprotection.com/support/kb/K9158.html

Sorry that I was not clearer in my question...I am looking for a service (not software) that I can direct my web traffic through from my router.  OpenDNS currently does this well, however their categories of internet filtering are very 'loose'.

At home have a hardware firewall (erased the linksys firmware on my router with the DD_WRT) and on each PC running microsft. I run the Comodo Internet security (both firewall and anti-virus) and implemented beside that Squid Linux proxy server.

Be aware open source firmware DD-WRT offers a number of builds, from a Micro and Mini generic with limited capabilities  all the way to a VoIP-specific and VPN-specific build. Fortunately, a chart lists  all the capabilities and various versions of DD-WRT  include  from Hotspot, IPv6, OpenVPN, PPTP, ProFTPD, SNMP, SSH, and Telnetd to a Samba/CIFS client. It has EoIP (Ethernet over IP, allowing you to bridge networks), VLAN, QoS, and advanced firewall (including the ability to block specific P2P networks).

To upgrade your router and make it more secure, I would recommend replacing the default firmware if you can. Make sure you check the compatibility lists!  

For filtering I use squid.....indeed squid is the best but keep in mind it requires times and skills to install, manage and configure it with other components. I used it in many complex environments with success but again you need  the skill in Linux and squid (open source packages)...
