Checked in VyOS 1.3.0
When Wireguard is specified as the uplink interface for dhcp-relay, isc-dhcp-relay cannot start. Consequently, dhcp-relay does not work.
set service dhcp-relay interface 'eth0' set service dhcp-relay interface 'eth1' set service dhcp-relay interface 'wg01' set service dhcp-relay server '10.1.1.111'
ISC-DHCP-Relay seems to be the problem (Unsupported device type 65534 for "wg01"):
