How to configure 2NIC devices

[bravo0916]

Hello Team,

I have just finished settiup Proxmox VE. Now, the machine has 2 NIC devices. I can see that there is vmbr0 has been configured already.
I want to setup another NIC device. Here is network map.

1. eno1 (192.168.50.xx) ->this is for servers and this eno1 has been sticked with vmbr0.
2. enp5s0 (192.168.30.xx) ->this is for local network and I will setup Windows VMs.

I just put IP address like 192.168.30.2 for esp5s0 and link is up now. I can ping to 192.168.30.2. I want to confirm if this setting is OK or not.
Or I still need to configure another brigde like vmbr1 and ens5s0 should be connected to vmbr1?

I appreciate your help!!

Regards,

Without a bridge VMs/LXCs can't use that NIC. So if you want to use that NIC with guests you should attach it to a new vmbr1 and set the IP on the vmbr1.

Hi Dunuin,

Thanks for your quick reponse. Now, I tried to setup as below.

1. enp5s0 ->all of the fields are empty.
2. vmbr1 ->I created this bridge and put 192.168.30.2/24.

The active status of vmbr1 is "No". However, I still can ping to 192.168.30.2. Do you know how I can change the active status to "Yes"?
Also, this configuration is OK?

Regards,

Whats the output of cat /etc/network/interfaces and ip addr?

Hello. Here is the output. BTW, I can not set GW for enp5s0 nor vmbr1. The error I got was "GW already exist on vmbr0". However, I think that I will need to set GW for 192.168.30.2 subnet.

BTW, I can not set GW for enp5s0 nor vmbr1. The error I got was "GW already exist on vmbr0". However, I think that I will need to set GW for 192.168.30.2 subnet.

Thats normal. There can only be one gateway where all packets, that are not part of the subnets the PVE host got an IP in, will be send to.

Outputs look fine.
