No problem, Another email has been sent 
Thanks again. Do you know how to set up a static ARP rule? The busbox shell doesn’t appear to support the arp command…
Alas I do not, as you know the DSL-AC88U never was a finished product, – forum member @chr7 was also looking at the ARP table to modify, so hopefully they managed to find a way and are still keeping an eye on this thread and maybe advise ?
