Squid Proxy configuration

Hi, I need help to configure a squid proxy (3.3) as transparent and tuning it at best. This is the situation: the proxy squid is v3.3, it is on linux machine. I need to configure it to connect from my home to this server, via ddwrt router. My home and this server are on a different net (obviously), i need this configuration to redirect all the traffic from my home thru this proxy server, but I wont configure the browser, I would like use the ddwrt router to redirect all the traffic. Th squid is already installed and configured to work normal. You should configure correctly the Squid proxy to work as transparent, configure iptable if necessary, and check the ddwrt router (it should be already configured)
