Thanks Kateedid
yes your modem is an issue. I have port forwarding instructions here:
Port Forwarding for the Motorola SBG900 Wireless Router & you should use
Port number 6346
After that, you'll need to adjust LW's settings to force ip. See
LW's Force IP instructions & sample image But if you've already done that then just double-cleck it.
You should be fine after this. Good luck.
