Routing traffic based off Domain Name?

[ionbasa]

So does anyone know how to do this? 

I have 2 FQDNs pointed to one server running Ubuntu. That server is running two virtual machines. I want example1.com pointed to VM1 and example2.net pointed to VM2. 

There is only one outside (WAN) IP. I have heard that this could be possible as long as the applications running on each VM have separate ports.

 

So any thoughts? 

 

PS: I asked on Ubuntu forums, people say it is possible, but nobody has posted any specifics.

Squid proxy server will be able to do this based on domain names depending on the kind of traffic. what applications/servers are you hosting?

 

IPTables (or any other firewall) will be bale to do it based on port numbers.

That is exactly what others have said. Now which module in specific?

It depends what you are hosting.

 

What services are you providing? How come youre using multiple virtual servers on the same physical hardware?

The reason I am using VMs is for sandboxing. This is a personal server. As to what services: MySQL, Apache, and a game server. 

 

My main thing that I want to achieve is to separate my game server to run off a different domain. The reason being is that I host my own personal website that is basically a portfolio of my professional and academic work. I don't want my professional domain associated with my game server.

Oh in that case it is really simple.

 

Just forward the port for the game server to the virtual machine that is hosting your game server. The domain name is irrelevant in this case.

That is what I am doing currently, but I want to give a VM a separate domain name.

W/ Apache, you can associate a certain domain name with a virtual server which you could use for your academic stuff, which would only server the files if the request is from X domain. Then point the game server address at your IP, and add another virtual server so that if they go to the FQDN in their browser they get a page.

Yes, I know. I currently have Virtual hosts set up. The issue is that there is 1 WAN IP.

Essentially what has to happen:

I need to figure out how to get Squid to proxy based on the domain name requested.

The domain name isnt used for routing. The IP addresses are.

 

Nobody is going to know that you have two different domain names pointing at the same address. The domain is only carried in the payload of packets where the application uses the domain name. It is 100% irrelevant in this case.

 

The best you can do (since you only have a single IP address) is to forward ports to your servers.

 

Squid is good at redirecting HTTP requests, and things like that, but you cant route packets based on things they contain in their payloads.

Yes, I now realize that. The reason being that most reverse proxies look at the HTTP header when determining how to route traffic. Sigh. 

 

Someone on server fault suggest using dual stack ipv6/ipv4. Each VM can get a dedicated ipv6 using hurricane electric's broker service. I can then use various 6 to 4 routes available as services, some even free. This would mean that I could tunnel to a different outside ipv4! Assuming I can set up various DNS records at my registrar, which I can.
