It looks like you selected the wrong network to assign the device to in the DHCP Settings portion of that screen. The network IP-range in the select bar next to IPv4 DHCP should match the IP range/address of the device. Is the ChromeCast's IP assigned by the Sophos UTM DHCP server?

You've lost us here Justin. 192.168.255.251 is not a public IP. If that is one of the interface networks on your UTM, your PC/phone will need to be on the same subnet to cast to your TV. 
 If I recall correctly, during setup, you assign your Chromecast a fixed IP. You don't need to have a DHCP definition, so just leave the DHCP settings empty. 
 Any better luck now?
