As the post title suggests  this is for users who would like to put their UPC Cisco EPC3925 modem/router device into Bridge mode without DMZ’ing and double NAT’ing This is the solution for everyone who would prefer not to use the UPC Cisco EPC3925’s builtin thin and terrible routing functions by using another router of your own  choosing to handle all of that for you while not having to DMZ or double NAT to get it to work
