the computer centre here has 20 computers. windows was installed in
all of them. one of them is a server with redhat linux installed. 10
of the computers are configured to connect to the internet. i
installed ubuntu on two of these computers. now the problem is that
only the windows computers or the linux computers are connecting to
the internet simultaneously. if i start a windows computer first and
start browsing, the linux ones wont connect, and vice versa. please
help. i configured the ip addresses for the individual clients and the
proxy ip number.
