Multiple DMZ? Possible?

First here is the Network Roadmap for my setup:

Virgin Media SuperHub in Modem Mode --> ASUS RT-N53 Router with 4 Ethernet Clients --> NAS SERVER + My Computer + TP-LINK Range Extender + PS3.

Now, I occasionally run a Game server from My Computer, which requires me to use DMZ to My Computer's local IP, however, I also want to run the FTP from the NAS server and to be able to access it from WAN.

However I don't want to have to switch the DMZ from My Computer's IP to the NAS SERVER's IP.

I'm no expert at all this networking stuff and I'm not even sure if what I'm trying to accomplish is possible with only one WAN IP.

I thought plugging both my computer and the NAS SERVER into a local ethernet switch would work but, after thinking about it again obviously that wouldn't help at all.

Any help would be appreciated :).
 
I'm not sure that the word DMZ is what you are really describing.

Have a look at logmein as that will allow you to access your home PC from anywhere. Also rather than leaving FTP open logmein can also allow you to copy files etc.

Or think about setting up a VPN that will allow you to "dial in" and become part of you home network.
 
On a home router the term DMZ means that all ports that aren't specifically forwarded will be forwarded to a destination address of your choice. As a result this means you can only have one address configured.

In a true firewall sense the term DMZ means something very different but that doesn't matter here.

The solution is to simply forward the port for FTP to your NAS and then leave your PC configured as the DMZ. This way the more specific mappings will take effect first and everything else is left to the DMZ.

I have tried to do that, but it simply doesn't get through, when I change the DMZ to the NAS Server it goes through all smooth, but then my game server can't connect :S.
 
Ah the problem was my ASUS RT-N53 isn't forwarding the ports. It simply isn't saving the rules I set it. I'll take it back to OCUK tomorrow.
