Bind9 becomes active

I changed the DHCP configuration on my current DHCP server. It now points toward the DNS server on this server. After a ipconfig /renew on my XP the DNS was pointing to the new DNS server. Unfortunatelly the ping did not work. In the log file I found that the firewall was blocking it. I added a rule to the firewall to enable port 53 and now it worked.

iptables -A ${LAN}_FW -p udp            --dport 53         -j ACCEPT

After this small victory I decided to put Squid into action (I installed it yesterday). I changed (through DHCP) the gateway to the router. Again the firewall blocked the requests to port 3128. I added the rule to the firewall and now Squid took care of the requests. But that was all. There is something wrong with the configuration of Squid. I get a web page with:

The following error was encountered:

    * Invalid URL 

Some aspect of the requested URL is incorrect. Possible problems:

    * Missing or incorrect access protocol (should be `http://'' or similar)
    * Missing hostname
    * Illegal double-escape in the URL-Path
    * Illegal character in hostname; underscores are not allowed

Now I have to find where the problem lies.
