One server with two public IPs

[wxipn]

Hi everyone,

i have one serveur, and 2 public ip. I would like to have one ip for my proxmox, and the second for all my vm, How can I set it up?

auto lo
iface lo inet loopback

iface eno3 inet manual

iface eno1 inet manual

iface eno2 inet manual

iface eno4 inet manual

auto vmbr0
iface vmbr0 inet static
    address .26/24
    gateway .254
    bridge-ports eno3
    bridge-stp off
    bridge-fd 0
    hwaddress :98

iface vmbr0 inet6 static
    address ::/64
    gateway ff

auto vmbr1
iface vmbr1 inet static
    address 192.168.50.1/24
    bridge-ports none
    bridge-stp off
    bridge-fd 0
        post-up   echo 1 > /proc/sys/net/ipv4/ip_forward
        post-up   iptables -t nat -A POSTROUTING -s '192.168.50.0/24' -o vmbr0 -j MASQUERADE
        post-up /root/dnat.sh
        post-down iptables -t nat -D POSTROUTING -s '192.168.50.0/24' -o vmbr0 -j MASQUERADE

I have an Nginx proxy manager, but it is configured to go to the primary address of the proxmox :81
I have a subdomain that redirects to my proxmox with my IP, how do I set up my second public IP? Should I create a new bridge? TY
