That is not an appropriate use of a range in the DEST of a DNAT rule.

From the documentation of the DEST column:

   Like in the SOURCE column, a range of IP addresses may be specified in the 
   DEST column as <first address>-<last address>. When the ACTION is DNAT or 
   DNAT-, connections will be assigned to the addresses in the range in a 
   round-robin fashion (load-balancing).

You need to configure your DHCP server to always give the same IP address to 
the machine running Arureus.
