2 Public IP`s to a single WAN

[LiorY]

Hello guys , I`m trying to assign 2 public IPs which I get from my cloud provider into the same WAN nic.
The problem I get is this, on the interface of the VM which runs on PROXMOX I get two IPs but both are the same while in the config.xml the configuration looks good I get both IPs in different sections of wan (wan and wan1) and I can use only 1 of them to connect into the GUI.
In the other hand inside the OPNsense GUI I can see the two WANs which in the settings I can see the IPs I got from the cloud provider.
Any suggestions of what the problem is?
Adding images if I didn`t clarify my self enough.

Don't create two interfaces - add the second IP via Interfaces > Virtual IPs instead.

I know I can do it from VIP but it doesnt show on VM interface.
