We have a Wireless router that we have installed Advanced Tomato on, and its connected to a Separate Network Service through our ISP, and gives us a separate public IP, (1.1.1.1), and were trying to configure this tomato router on 1.1.1.1 so that a specified internal address or address range can have access to network services on the other network (2.2.2.2), to achieve this what configurations do we need on the tomato router, 1.1.1.1?
