Nixie155: Your Router does use NAT which can block many ports. I don't have specific instructions though how to allow LW access by using port forwarding. I did find this however: http://www.adsltech.com/faq/ 2/3 way down the page it discusses about setting up a static ip which yo need for port forwarding & further down a bit is about forwarding a range of ports. All you need to do is forward a single port: 6346 & if necessary add the application name (some routers have that option.)

Then you can force ip within LW: Force IP instructions & sample image

Doing these things will clear a way for LW.

Do you use your modem in ethernet or USB connection. Wisest is ethernet. It's not only faster but many USB routers suffer 2 problems: 1.obtain power from comp. 2. utilise comp's processing power thus draining your comp of 'some' speed.
