How to give access to virtual machines behind NAT by domain name?

Question

Domain Name System

Good afternoon.

I want to start a small zoo of virtual machines at home: nas4free. centos with Bitrix VM, opds server. But there are questions about setting up access to the necessary services from outside.

Let's say there is:
- external white IP 111.111.111.111
- domain.ru domain
- a server located on the home network behind a router with virtual machines:
1) nas4free with ip 192.168.0.1 (nas.domain.ru)
2) Centos with ip 192.168. 0.2 . It has a web server with three sites that I would like to have access to via dns:
-a) test1.web.domain.ru
-b) test2.web.domain.ru
-c) test3.web.domain.ru

How to organize access to all this from the outside?

Answer 1

set test*.web.domain.ru domains to a white address. If all sites on virtual machines should respond to port 80, for example, then install nginx frontend on the root machine and proxy to virtual machines.
