[Network] Redirect domain to a guest VM inside server

[Thireus]

Hi people,

I'm running Debian 6.0 and I'ld like some tips or clues regarding DNS and basic networking.

I'ld like to achieve the following thing:

I have a server which owns a unique IP address and domain name, let's name it thireus.com.
I also have some virtual machines inside it, managed by qemu, and I want to access them from the outside.

thireus.com --> server.ip
vm1.thireus.com --> server.ip --> (sub-network) 192.168.1.101
vm2.thireus.com --> server.ip --> (sub-network) 192.168.1.102
et.

Do you know how can I do this?

I don't want to play with port forwarding, so that I can have a website and sshd running on vm1.thireus.com and another sshd and website on vm2.thireus.com.

Thanks for your help

You won't be able to get inside the guest vms without port forwarding.

One other solution would be to set up a VPN server on the main VM, connect to the VPN from the guest VMs and from your PC then connect to the VMs via the VPN

The services running on the VM are supposed to be publicly accessible on the Internet. I already managed to poxify the 80 and 443 ports with apache using mod_proxy, so that subdomains vm1.thireus.com and vm2.thireus.com for port 80 and 443 reach the VM apache services.

But how can I do the same for SSH? So that if a client types 'ssh user@thireus.com -p 22' he reaches the sshd of the server and if the client types 'ssh user@vm1.thireus.com -p 22' (same port) he reaches sshd of VM1.

Is it possible?

Unfortunately I don't think this is possible for SSH without port forwarding and different SSH ports for each VM.
