Proxmox 4 - Problem with IP and containers

[Niloc]

Hey,

I set up a host node and I wanted to create a container with 1 ip.
In proxmox 3 i could just type in the IP. In 4 it wants me to add (for example) /24 after the ip. So if I put a /32 behind it, it should have 1 IP.
The problem is, that the costumer can change their ip from xxx.xxx.xxx.100 to xxx.xxx.xxx.120 and it still works for them. They can even type in that IP if it's already used by another costumer.

How can I prevent users from doing that? Or how can i set up a container with 1 specific ip?

Thanks.

Hi,

i think you understand something wrong. "/24" is the subnetmask. This is "255.255.255.0". You have writen "/23", this is 255.255.254.0" This network have 510 adresses. So it is depending on your net, it is another way of writing. /32 is not one IP.

Do protect customer to change this use the ACLs: https://pve.proxmox.com/wiki/User_Management#Privileges
We do this in this way, and it is working fine.

Best Regards
