A problem with Mandrake multi network firewall
 

Hi guys,

I have a pc running mandrake firewall, the proxy that it uses is squid.
i have 3 network interfaces on this pc, eth0 is hooked up to lan, eth1 is hooked up to wan and eth2 is hooked up to the dmz. My network address is 192.168.1.0 and every one in that network can access the net through squid. However there is also another network 192.168.5.0 and if anyone tries to access the net under that address it shows up with

ERROR

The requested URL could not be retrieved

--------------------------------------------------------------------------------

While trying to retrieve the URL: (url goes here)

The following error was encountered:

Access Denied.
Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Your cache administrator is root.

I have tried everything and cant give the network 192.168.5.0 access to the internet. Could some please help

Thanks
