I know that NetBIOS is not supposed to be a routable protocol. However; I have made samba work in lab environment where it spanned across two routers. What I want to do is make it so that my linux server can be accessed through my router from the internet. I have setup samba so that any computer on my lan access it. I then forwarded ports 137-139 to my linux box on the router. This method has worked for telnet, ftp and ssh so it seemed as if it should have worked. Has anybody made this work or have any ideas? Thanks a lot.
