Title: Use IPS from other VPS on my main server? IPv4

Situation:

Subservers:
3 VPS servers each at different provider.

Main server: 1 VPS running directadmin the provider can't do an extra IPv4. I want to add the other VPS ips to direcyadmin (no need to do anything else on the VPS) as long as i can use the IP from it on the Directadmin mainserver.

Any direction on how to do this? Running centos7 on all.

One provider will not allow you to map their IPs to another. Even if you add them in DA, they will not resolve to your server.

Yes but not directly, but i'm just hosting a VPS, so can i forward it on a VPS to another one?

I'm not sure what's your use case but I guess CloudFlare would be good solution for your problem. There is really no trivial solution for what you need.
