setting 2 Squid proxies

[amavis_user@xxxxxxxxxxxxxxx]

Hi,

We have following setup:

A LAN comprising of 15 PCs with a server connected to internet running  
squid as a  transparent proxy.The server has ip 192.168.0.1.

I want to configure another machine on the LAN which is not connected  
to Internet directly like the server as a proxy for other machines on  
the LAN.Is it possible to do so ?

Thanks in advance.
