[SOLVED] No IP from DHCP server


Jun 21, 2020
Well, seems like its only the VM that does not get an IP address. Other VMs get an IP address from the second network card.
For the VM, the interface / card was visible, but I had to add a new connection with nmtui. After this, the device was listed in nmtui as beeing activated. Also shows this at nmcli -p dev. Now it has a second IP address.

Hello, I bought a second network card (Intel I350) with a quad port. The first one works great, and I get an IP from my DHCP server. However, for the second card, I do not receive an IP address. This is basically the sane fir every vmbr, except for the port / interface:

auto vmbr1
iface vmbr1 inet manual
bridge-ports enp2s0f0
bridge-stp off
bridge-fd 0

May 04 17:02:13 pve-1 kernel: igb 0000:04:00.3 enp4s0f3: igb: enp4s0f3 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
May 04 17:02:13 pve-1 kernel: vmbr3: port 1(enp4s0f3) entered blocking state
May 04 17:02:13 pve-1 kernel: vmbr3: port 1(enp4s0f3) entered forwarding state

- Proxmox does see and recognize the second card @ lspci
- Proxmox shows a connection on the card, and says: entered forwarding state
- Using the first network card to the same port as the second network card to the switch, provides me with an IP address.

- nmcli tells the interface is 'disconnected'
- The other interface (other network cad) for the same VM tells 'connected'

- The switch notice a 1000Mbit connection that port, also at another port.
- The router does not receive a DHCP request

This network card in another system with Windows:
- does get an IP address from the DHCP server on every port

Another PC connecting to the same switch:
- does get an IP address from the DHCP server

To me, everything looks fine, but somehow something doesn't communicate with the second network card.
