I have been battling with this for over a month any configuration on my VM's does not seem to fix my issue.

Below is the image of my network setup provided to me with a deployment of Proxmox from my dedicated server host.

eno1 & eno2: These are my 10Gb connections
bond0: eno1/eno2 bonded
bond0.10: Seems to be my internal network as that is an internal network provided by the host this specific proxmox instance is assigned the shown IP
bond0.3: Not sure what this is but its VLAN 3 and shows up in my server configuration on the hosts control panel, I have 2 other servers both with vlan 2 and 4 provided.
vmrb0: this is the connection utilizing my public IP which I am able to access everything including in shell pinging my other 2 servers on the internal network of 10.0.0.11 and 13.

My question is I want to add additional devices not utilizing additional public IPs how do I give them an internal address to be able to talk to my other servers and utilize lets say 1 public IP amongst all of them for updates/download etc. I understand in the screenshot I have a /31 and thats only one useable address, but I do own larger blocks which I would use to implement whatever the change is that I need to make.

my current setup is every VM gets a public IP and I have firewall rules to block all outside traffic. This gets expensive especially when I have VMs running monitoring agents that I dont need a dedicated public IP for since they are internal tools.

Any help would be greatly appreciated.

U create a 2. Bridge for vlan 10. There u can connect the VMS & co. For internet u must forward this net over vlan 3. This can be done by a router VM like opnsense or u use some iptables rules in the interfaces file. U find examples in this forum.
