Reverse proxy for VMs

[egrueda]

Hi all.
I'm playing with a Proxmox VE dedicated server. This server has just one public IP, so all VMs are using privated IPs (192.168.1.x) and MASQUERADE on proxmox host.

I want to access several name-based virtual hosts in several virtual machines, so I need this configuration:

www.example1.com => proxmox.example.com (11.22.33.44) => Virtual Machine A (192.168.1.11)
www.example2.com => proxmox.example.com (11.22.33.44) => Virtual Machine A (192.168.1.11)
www.example3.com => proxmox.example.com (11.22.33.44) => Virtual Machine B (192.168.1.12)

see? a single public IP which reverse-proxies all HTTP requests to their corresponding virtual machine.
I'm using nginx, which listens on public port 80 and acts as a reverse proxy, as nginx supports name-based vhosts.

Ayway I'm having some problems to make it work correctly.
Someone of you is using or has used this same method? any nginx + nat solution?
Thanks!

Hi,
i use pound for things like that (but not for proxmoxstuff).
This example is for URL-Based reverse-proxying:

ListenHTTP
        Address IP.ADD.RES.S
        Port    80 
        xHTTP 0
        Service
                HeadRequire "Host: *.www.domain.*"
                URL ".*WebContent//*"
                BackEnd
                        Address 192.168.99.5
                        Port    80
                End
        End
        # anything else local
        Service
                HeadRequire "Host: *.www.domain.*"
                URL ".*"
                BackEnd
                        Address 127.0.0.1
                        Port    8080
                End
        End
End

Hi, Udo, thanks for your answer.
I've tried pound before, but was looking for a cached proxy so it's not valid for my needs.
Anyway when I tried pound is was a really quick and easy proxy (maybe even too simple) and worked perfectly ;-)
