[SOLVED] Using a NIC with dual ethernet connection

[MiguelNdeCarvalho]

you need in my opinion remove the bond and then dedicate one interface for management and the other for your virtual machines. i should have a screenshot of how I would set it up shortly

like this?

 

[MiguelNdeCarvalho]

Because in each VM I am creating a static IP instead of having dhcp

 

[Astraea]

you will want to change the ip of vmbr0 to your management IP but do not assigned an address on vmbr1, you would assign the ip inside the vm(s)

 

[Astraea]

what you have in your screenshot is an IP assignment for the node, then the same IP assigned to 1 or more VMs

I am rebooting the NODE right now. But I think all is fixed. Really thanks for the help

Thanks god that I didn´t apply the config

glad you got it working again. just remember to edit your original post and mark it solved after you make sure it's working after the reboot.

Management interface is where it should be (using vmbr0 now), now I am trying to setup the interfaces (with vmbr1). But when I try to ping a host it simply fails.

 

[MiguelNdeCarvalho]

But I the internal ip is correct, but when I try to connect via ssh it fails

Post a screenshot of the VMs network interface file as well as a screenshot of your nodes network settings in the proxmox web interface. Let's see where the issue is hiding now.

 

[MiguelNdeCarvalho]

Here it is. My network setup and then I am showing the VM config

 

[Astraea]

If you goto the console for that vm and login, I assum a linux distro. Can you screenshot the /etc/network/interfaces file contents for me.

Two things can you ping either the proxmox node or say googles dns server from the vm?

What is the output of this command: ip addr show when run in the VMS console

Just confirming that your second nic port is connected to the same switch or router as the first one? They are 2 separate cables correct?

Yes there are 2 separate cables. Tomorrow I am going to check that and I will give feedback here. Thanks for help. Bye

Hey, I forgot to plug the cable xD, thats why it wasn´t working. Thanks for the help. Bye
