Servers configured with DHCP have a default route in the corporate network. Every time a "new" host is connected, a "no route to host error" is received. The second request after a few seconds works fine. This happens most frequently on port 443.
How can this be fixed, as the firewall used is a checkpoint firewall and there is no further information in the log files. Is there a linux command to trace the error constantly, as this only happens every time the host is unkown.
As I am not an Network engineer I just need a way to gather more information for the specialists.
