Unable to DHCP on different nodes

[techstackstudios]

Hi Everyone,

As an exercise, I have a 3node cluster running a simple SDN setup. I disabled autoDHCP and setup a windows DHCP server. When I install a client machine on a different node it is unable to get DHCP but when I migrate it to the same node as the server it works. I have disabled all firewalls so there should be nothing blocking either.

Any ideas?

you didn't say what your "simple SDN setup" is. Look in https://pve.proxmox.com/pve-docs/chapter-pvesdn.html.
Simple Zones don't work inter-node. I use VXLAN and DHCP works fine with containers/VMs in the cluster.

Using SDN across nodes the switch has to pass the VLAN tagged packets.
