The linksys router (wrt54g) is currently the only router whose wan port is connected to the internet (cable modem). The linksys lan ip is 192.168.3.1. The netgear's wan port is currently plugged into a lan port on the linksys. Netgear wan ip is 192.168.3.50. The lan network on the netgear is 192.168.88.0. The netgear provides access to this network via it's connection to the linksys router. I am trying to get to a share \\192.168.88.88\QB on the netgear lan from a computer (192.168.3.88) on the linksys lan. I've tried unsuccessfully adding various routes but have had no luck. I'm not sure whether I need to add routes to the routers, the computers or both. I'm not even sure if this configuration will work with these type routers. I'm using this as a temporary setup until the ISP hooks up internet connectivity for the Netgear, but even when this is done I plan to connect a lan port from the netgear to the linksys and allow 192.168.3.88 to connect to the share \\192.168.88.88\QB. I'm trying to keep them on separate networks because they are separate businesses with the need to only share one file.
