TFTPD64 4.62 DHCP reports BOOTP/TFTP server address incorrect

I've bound BOOTP/TFTP servers to specific interfaces. Let's say 10.0.1.2. There is another interface on the computer, 10.66.66.2

Device gets DHCP address and TFTP address as 10.66.66.2.

Must turn down the 10.66.66.2 interface to allow client to access correct 10.0.1.2 address for the servers.
