Automatically detect settings ?

[ethraza]

Hi! Look that... :unsure:

 

I have a server with isc dhcpd, squid, shorewall and apache.

I have that virtual ips and that dhcpd subnets so the clients cannot see each other. This is working. My only problem is the authenticated proxy part.

If I don't use authentication, it become simple. Only a trasparent nat or redirect to port 3128 will work. But if I ant to make the browser require user and pass, it become a little bit more complicated.

This is become hard everyday and I become more

 

My wish:

That clients can be a new notebook everyday and the only thing that I want to support the owner of that notebook is to put the tcp/ip in dhcp mode to boot in my net. And maybe to put Automattically detect settings in the M$ IE Lan Settings.

The notebooks will not see each other. They will see only the server and the proxy that is responding on 3128 port and is authenticating.

 

My problem:

Neigther IE or Firefox see the proxy.pac or wpad.dat on my gw server.

That proxy server is authenticating and the user must enter username and password to go to internet.

The only way to get this work now is manually seting the proxy ip and port on the client. But I don't want to do that. This need to be a automatic thing.

 

 

My configs for now:
