We using Linux CentOS.
For example - we have 3 hosts - host1.domain.com, host2.domain.com, host3.domain.com. Hosts connected via VPN.
Task: host1.domain.com must be a gateway for http/https traffic, and redirect requestes to host2.domain.com and host3.domain.com.
host1.domain.com will have external IP and accepts request on 80 port.
host2.domain.com and host3.domain.com - internal IP and accepts request on 8080 and 8443 ports.
How this can be realised? IPTABLES, NGINX, something else?
And - what about other traffic? SSH, samba etc.
