[squid-users] a problem with access denied

Hello!

Just subscribed to the list because I have a problem with Squid
on my firewall.
I configured Squid as accelerator to Apache inside the LAN.
The following iptables-rule works so far:

iptables -A FORWARD -p TCP -d 192.168.1.3 --dport 80 -m state \
          --state NEW,ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A PREROUTING -p TCP --dport 80 -m state \
   --state NEW,ESTABLISHED,RELATED -j DNAT --to 192.168.1.3:80

I can get with Netscape to Apache accesing the firewall on 192.168.1.210.

But now the problem. As soon as I configure the proxy in the Netscape
cache-settings I get an Access denied.

I don't understand what is going on. When I insert the URL of my
firewall with the proxy-port http://space9.meyer.home:3128/ everything
is ok and I'm forwarded to Apache.

Can someone help? I increases the logging and cannot find anything
unusual. It makes no difference if I set http_access allow all or
http_access deny all as last rule.

I'm completly clueless.
