Remove the restriction for RFC1918
In the most recent patch for K1000 (6.4.120756), Dell added a restriction that prevents the use of certain IPs. This change was not disclosed in the release notes and almost had a significant impact on our network. We now have to run a limited DHCP scope (where we would prefer not to) to accomodate the KBOX and our IP scheme. Please, Dell, leave the networking to us!
