I've tried what you suggested Roland, and there has been some improvement in the following areas:
- I am able to telnet into my linux box from other computers in the network
- I can ping the linux box
However, I still can't open my shared files :unsure:. I suppose I have to modify something else as well. I would like to show you a part from my /var/log/boot.log file, a part that has to do with the shorewall (I've bolded the part I find fishy, please let me know if you see something else):
