After reading my own source again I realized that the thing I want is not possible. It goes beyond the goal of splitting the network into different segment. If all arp request are being forwarded to other networks there is one advantage less: you want to keep broadcast domain small.  Static arp is the thing I'll need to implement to work around this. Thanks for the clarification anyway.
We need to enable some clients to resolve the mac adress of a server which is in another VLAN and ip address range. I thought that adding the command ip proxy-arp to the vlan interface should do the job, but this command seems to be enabled by default according to the reference guide, after I tried to add the command it is still not shown on a show run. That was confirming my thought. While I was looking for the solution I saw another command which is not listed in de cli reference guide: ip local-proxy-arp. But since I am not sure what this command will do I am cautious to just hit the command on the interface VLAN. How do others route their arp requests on powerconnect 6224's?
Proxy-arp or local-proxy-arp??? Dell Powerconnect 6224
