Actually, my internet is given by BSNL's ISP; it is NOT a private network I believe. I use mainly Ubuntu; and I put IP, netmask, default gateway and two dns. It works just fine!

But I can't understand what is going on in Knoppix.
In my modem configuration I always disable DHCP.

Could you kindly instruct me further?
