[故障求助] Transparent Proxy in the DMZ Zone

Hey everybody. I currently have the DMZ, Trust & Untrust zones configured in my Netscreen 25 Device. In the DMZ i have the Squid (Proxy) Server listening in the 3128 Port. I want to redirect all the HTTP Traffic that tries to get From Trust to Untrust to the Proxy Server located at the DMZ.

I tried with the following command, but it didnt work:

set policy from "Trust" to "Untrust" "Any" "Any" "HTTP" nat dst ip <proxy-ip> port <proxy-port> permit log count


I'll appreciate any help.

Thanks
