How to properly add and configure a network card in Proxmox?

Question

Debian

Good time of the day. How to add and configure a network card in proxymox?
The bottom line is that I installed an additional network in the server, the main network network is already configured on the 192.168.2.0/24 subnet + 2 vlan 101.102 with this network everything is OK, it works properly, I need to configure the new network on a different subnet 192.168.200.0/24 she will not have access to the Internet; he is not needed there.
I added vmbr1 and configured the IP on it, but when the server is restarted, the first network network on vlan 101, 102 stops responding. Where do I need to correct it? Thanks in advance for your reply

Answer 1

Himself Asked himself answered. If you have N + 1 network cards, where 1 is your main one, and you want to connect the SAN to the server, write down routes to the storage via dev ethN, you do not need to create vmbr.

Answer 2

go to interfaces and fix it there
