Best of luck with it my man, seems alot of people are looking for this answer, There must be a way to workaround the dynamic arp on home routers , the issue leans more in the direction of the routers not holding static arp tables , I can bet you if you can enable static arp that this issue should go away maybe Dlink can do that for you

( Standard expectation of home routers are that you'll have one port targeting one device and not two this is the hurdle that is catching both MS and home router makers i guess)
Is this even possible? Maybe the guys at dlink can answer this for you.
