Hi Rick,The SGOS Admin Guide is probably going to be the closest thing for what you are looking for. Chapter 6 goes over the different explicit and transparent (inline, WCCP, etc) deployment options. Also, in different sections in the entire guide, it will tell you how to set things up explicit vs transparent. https://techdocs.broadcom.com/content/dam/broadcom/techdocs/symantec-security-software/web-and-network-security/proxysg/6-7/generated-pdfs/SGOSAdmin67.pdf
Hope this helps!
