Squid proxy and SonicWALL
My network is:
ISP --> SonicWALL--> Proxy --> LAN
Currently Sonicwall is running VPN, DHCP, port forwarding etc.. in a range of 10.0.0.0/24 and I have tried to configure Squid Proxy for content filtering (using squid 3 Transparent mode on Fedora 10 and Iptables) .
Now I need to implement the proxy over my network without changing the SonicWALL current settings (VPN, Port forwarding and DHCP).
Thanks in advance!

The documentation is always helpful:

I have already configured my Squid proxy for content filtering and tested over my lan manually. But now I want to implement proxy server over my network and wants all request (http) to go via proxy only.
Can anyone help me to place my proxy over the network behind SonicWALL without changing my current settings?
ISP-->SonicWALL--> Proxy --> LAN
If I place the proxy just behind SonicWALL, what rules do i need to add to redirect http (80) to proxy's port (312.
Thanking you in advance

A forwarding rule should do the job. Basically you would redirect all outgoing traffic from port 80 (http requests of LAN clients) to your proxy. See your firewall documentation how to configure a NAT port forward from SonicWall:INPUT/80 to Proxy:3128. Make sure to not forward port 80 requests from the Proxy to the Proxy itself, as it would produce an infinite forwarding loop.

Even though the document above is rather outdated, it provides you with all the information you would need to configure an iptables firewall properly:
Transparent Proxy with Linux and Squid mini-HOWTO: Transparent Proxy to a Remote Box
I simply don't know how to configure it on your firewall.You've gotta find that out on yourself.
