DNS server
i need to have multiple servers on one ip. how would i achive that say by dns or something so that each server is accessible by the same port.
for example
Server1: mydomain.com -> local 192.168.1.12
Server2: s2.mydomain.com -> local 192.168.1.13
is this possible by windows dns or linux, any method really would help.

Just assign multiple IP addresses to your system. That generally isn’t a problem. Just about every network adapter will allow multiple addresses: multi-homing. — Tom
Do you mean – external access to a single IP but behind the firewall there are three servers?This is a Network Address Translation (NAT) address
One router, one WAN IP. multiple servers behind a firewall on same portsfor example two webservers
If they must be on the same port numbers, then you need to assign a different IP address for each one. Multi-home the adapter. — Tom
Multi-home the adapter???
First, if they’re going to be using the same port, they can’t have the same IP. (Well, that’s not totally correct; but if you’re not familiar with multi-homing, it will be much harder to implement the sockets programming that would be required to manage the packets and essentially proxy them to the underlying processes.)
So, you need to use two IPs for the adaptor. With Windows, it can take some poking around to get it done unless you have utilities that can do it for you. See Configure TCP/IP to use DHCP and a Static IP Address at the Same Time for one description of how to add IP addresses for an adaptor.
But re-reading your question makes the actual requirement unclear. Under ‘Software/Hardware used:’, you had ”NO os”. Does that mean you have no OS on the box? What exactly are you trying to do?
