@Philbert Yes, editing the reserved IP address in the APP after it has been assigned by the DHCP server is working well. Thanks for making the suggestion.

@Philbert Thanks for the suggestion about editing the reserved IP address's as I didn't realise that was possible. Will give that a go later tonight.

I have two QNAP NAS devices on my home network and and number of printers that I want to assign them with static IP's. Have three X20's units installed, the main x20 unit is running in router mode...
