I set up the PiServer tool on a VM and configured it to act as DHCP relay, but I need it to boot clients from multiple subnets. I attempted to set up an ip helper, but I have been unsuccessful in getting it to work on any subnet other than the one the PiServer tool is on. With that in mind, is it possible to configure it to listen on multiple interfaces if I add a NIC on a different subnet? I know it's not possible in the GUI, but I am hoping I could change some settings on the backend to get it to work. Thank you.
