I am assuming that you are within your firewall so ports 8192, 2068, 3211 shouldn't matter that they need to be opened. i would recommend right clicking on your remote console switch in the software and checking the network properties to make sure that you have the proper IP address. If it is correct then use a x-over cable and connect directly from a laptop to your ethernet port on the back of the Dell KVMIP switch to verify connectivity. From their you may want to check your ethernet switch and KVM switch are matched in network speed/duplex settings.
