limiting clients behind a BEFsr11 to just a couple sites?

    I have a need to block ALL websites but 4 -10 that I want clients behind the BEFSR11 router to access. Can I do this w/ the router or should I try someting else?

    I really dont want to put a proxy server software on one of the computers behind this router if at all possable.

    Any comments and/or suggestions would be helpful.

    well if you don't want to run a proxy behind the rotuer I don't think it's possible linksys usually does blacklisting rather than whitelisting in their access control, you could do it with a WRT54G with custom firmware and iptables rules but afaik you can't do what you want with that router by itself.

    Thanks for the info. I have a couple WRT54G's w/ sveasoft Al6a running. Testing throughput and uptime reliability, due to post here and in other forums, before i put in production.

    I havnt even looked at iptables or configuring them. Would there be a tutorial or post somewhere on how to do this?

    Thanks for the info!

    i've never used Alchemy for any period of time but i'm sure it's pretty stable being as like everyone is using it...
    iptables is pretty easy to use for something basic like what you want...
    heres an example taht should work:

    iptables -I FORWARD 1 -d allowedip -j ACCEPT
    iptables -I FORWARD 2 -d allowedip2 -j ACCEPT
    iptables -I FORWARD 3 -d allowedip3 -j ACCEPT
    iptables -I FORWARD 4 -d ALL -j DROP

    (this will also block access to router though so don't make this perm until you've tweaked it a bit)
    (something very similar to this anyway)
