Forward ports for a site on a virtual machine?

Question

Debian

The situation is this.
We have a dedicated server. It has 2 virtual machines. On one, all sites to which port 80 is transferred. And on the second there will be only one site, with specific settings. But how to forward ports so that when this site is requested, a request would be made to the second virtual machine?
UPD: There is only one external ip

Answer 1

You can put a web server ahead of everything with proxying.

Answer 2

Proxy through nginx. Delov for a couple of lines then =)

Answer 3

We put nginx on any machine, add 2 configs:
#server1
server {
listen 80;
server_name server1.domain.name;
location / {
# pass the hostname to the remote server
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_pass http://10.10.10.1;
}
}
And the second config by analogy.
