Hello I just bought a very cheap OpenVZ, it turns out that this vps the ip is shared between the users, each user has a port range available
What I want to know if it is possible to redirect port 80 of the domain to the port that I have open with apache
For example
mydomain.com:80 ip.publica.del.host:5712
Only that I would like to know
The quick answer is NO. But there are several alternative solutions that could help you alleviate the problem.
The problem is that the browsers do not even have support to interpret the DNS records called SRV that could give a direct solution to your problem.
Its use, hypothetically, would be as follows:
# _servicio._proto.nombre. TTL clase SRV prio peso puerto destino.
_http._tcp.midominio.com. 86400 IN SRV 10 10 5712 dns.publica.del.host.
As I say, the problem is that there is no support in the browsers for that extension offered by the DNS service, so other solutions are usually used.
One of them could use one of the many free redirection services (or with very small advertising or fees) that allow to integrate in an HTML frame ( <frameset>/<frame> ) a URL (which could be http://ip.publica.del.host:5712 ), a redirection HTTP (header Location ) or other similar systems.
Examples:
There are also CDN services (but usually they are usually paid, free ones do not usually support it) that allow you to configure the engine (backend) with non-standard ports, just as you also have the possibility of using a reverse proxy on another server dedicated you have.
