With a static IP4 address, I attempted to change OMV's DNS server address. The change refused to save, with the Gateway address highlighted in red, as if there was a fault. There error remark is "This field should be an IP4 address". Has anyone else seen this?
The only way this dialog saves, that I've found, is when the Gateway address matches the DNS server address.
(With OMV3, I can set DNS servers to any address.)
