Web Access Whitelist Problem

    Hi all,

    I am trying to write a script where a whitelist defines the allowed hosts for web access. I'm creating a restrict chain, which gets called for a given ip address (will change that to a mac address when it is working).

    WHITELIST='.wikipedia.org$ ^dict.leo.org$'
    # split string
    WHITELIST=`echo $WHITELIST | awk 'BEGIN{FS=" "}{for (i=1; i<=NF; i++) print $i}'`
    # this is needed for the iptables web module to work
    /sbin/modprobe ipt_web
    $IPTABLES -N restrict
    $IPTABLES -I FORWARD -s -j restrict
    $IPTABLES -A restrict -p tcp --dport 53 -j RETURN
    $IPTABLES -A restrict -m state --state RELATED,ESTABLISHED -j RETURN
    for host in $WHITELIST
      $IPTABLES -A restrict -p tcp -m web --hore "$host" -j RETURN
    $IPTABLES -A restrict -p tcp -j REJECT --reject-with tcp-reset
    so the restrict chain looks like that
    # iptables -L restrict
    Chain restrict (1 references)
    target     prot opt source               destination
    RETURN     tcp  --  anywhere             anywhere            tcp dpt:domain
    RETURN     0    --  anywhere             anywhere            state RELATED,ESTABLISHED
    RETURN     tcp  --  anywhere             anywhere            web --hore ".wikipedia.org$"
    RETURN     tcp  --  anywhere             anywhere            web --hore "^dict.leo.org$"
    REJECT     tcp  --  anywhere             anywhere            reject-with tcp-reset
    My problem is when I run the script on the router, the client with the ip-address can not surf anywhere.:frown:
    Maybe someone could look at this and give me an advice how to solve this problem.
