      <br>
      See the response from Simon. I am also not familiar with
      redhat/centos/Fedora, so no idea where the script will be located.
      This script is called by dhclient to do that actual configuration
      work. <br>

                <br>
                I would suggist to find a strong cup of coffee ;)<br>
                <br>
                DHCP is designed to work with no IP routing  in place at
                all. Please consider that DHCP provides the computer
                with the IP address it is to use. Any gateway is
                dependent on that IP address and CANNOT be assigned
                before the IP address is known. <br>
                <br>
                The correct question is indeed posed by the OP, which is
                why the gateway is not applied from the DHCP response. <br>
                <br>
                Some questions:<br>
                - which distribution is this?<br>
                - is dhcp provided by the a package from the
                distribution, or is it hand compiled?<br>
                - which release of dhclient/dhcp is in use?<br>
                - dhclient typically calls a script to set the values.
                Is this script correct and in place?<br>

                            the server, and the guy at the other side
                            tells me that each time I try to remove the
                            route the default route becomes a star
                            (**default ***). I'm obliged to let him add
                            the route again mannualy, and when I'm
                            connected, and I restart the network I lose
                            the connection again.</div>
                          <div><br>
                          </div>
                          <div>So my questions are : </div>
                          <div>1) Why does this unspecified default
                            route come back every time?</div>
                          <div>2) How can I (what's the way to) remove
                            it without spoiling the routing table
                            (losing the good  default gateway).</div>
                          <div><br>
                          </div>
                          <div>Thanks.<br>
                          </div>
