Specs: Windows Server 2008
We are trying to set up a system whereby a packet going to a subdomain on a particular port can then be internally routed to a particular machine.

So, imagine we have, we can set up on our ISP that goes to (One of our IP addresses). Our firewall is then set so that any traffic going into this IP address is forwarded to our domain servers internal address of We then want to be able to set up a DNS forward zone, so that it will look at this packet, recognise it as being, and forward it to the machine on

I've set up the ISP and firewall side OK, traffic to ends up at the domain server, but the DNS forward zone setting isn't working.

DNS doesn't route. Routers do.

DNS forwarding is all about load balancing requests. For example if you have multiple domains but only want one dns server resolving internet requests you configure the other dns servers to forward their internet requests to this one dns server.

correct configuration is to have the firewall forward this port to not the server. You do not forward all traffic but only do port forwarding.
