Hello,
since Proxmox 5.x my DHCP won't work anymore. I still use a proxmox 4.x-Node in my cluster to have the option for dhcp.
Proxmox 5.x Node
/etc/default/isc-dhcp-conf:
eth1 -> Private VLAN
/etc/dhcp/dhcpd.conf:
My KVM-Guests (using vmbr0 -> public-interface Intel E1000) won't get any IP-Adresses
With Proxmox 4.x all is working fine:
There is no /etc/default/isc-dhcp-conf
/etc/dhcp/dhcpd.conf:
Host:
eth0 - public
eth1 - private
vmbr0: public
vmbr1: private
Hope to get help from you, guys.
Thank you!
