FALSE is a bad sign!!! And Linksys modem/routers use a type of firewall. I think you'll need to open a port (ie: forward a port) within your modem to allow LW total access in & out wards. But to help you do this you need to tell me the model no. It'll be on the top or bottom of the modem most likely. Once I have that I can give you instructions on how to open the port for LW on your modem.
