Proxmox 5.4, adding additional IP's

[root012]

Hello,

When I upgraded promox 4 to 5.4 I can't add additional IP on my LXC server, when I add +2 IP he is offline, when I extinguish eth0 via nmtui, eth1 works, on VPS only one IP can works. I don't know why and can't find reason... Could you please help me?

If you are altering config files managed by Proxmox VE (eg. network), then you need to set the ignore file for the specific config file.

Thanks, but no luck.

I also tried to use KVM but the same thing, I use nmtui when I disconnect my primary IP address my second IP address works, but when I connect the primary again, the second IP stops working. Only one IP address can work, multiple IP addresses cannot be activated.
