I am running VyOS as a live disk with 2 physical ethernet interfaces. The first network interface hosts a 10.151.X.X subnet. This network interface is used for SSHing into VyOS. This IP is statically assigned.
The second network interface hosts a 192.168.0.1/16 subnet. This is the network interface that needs to supply IP addresses via DHCP to other clients on the network. I have the physical DHCP network interface connected to an 8-port unmanaged network switch. This network interface is also statically assigned.
The unmanaged network switch is connected to 2 ubuntu linux clients. Currently, neither DHCP client is receiving an IP address from the DHCP server. I checked the client systems and none of them are receiving an IP address from the DHCP server.
I am able to, however, assign a static IP to the 2 clients to get the clients manually (using sudo ip addr add ip/netmask dev device) to ping each other and the VyOS static IP 192.168.1.2/16. This makes me think that the hardware is not a problem.
What do I have to do to get the DHCP address assignment to work? At some point I would like to have both static and DHCP IP leases, but I figure I should get DHCP working first.
This is the version of my VyOS instance:
