multiple DMZ's?

[heymrdj]

I run VMWare Server here on my laptop. When I was running a regular webserver as a VM, I would set my router to DMZ the static IP I gave my VM. But when I want to run multiple servers (like testing the layout of a apache setup proxied mongrel and balancing from a postgresql server and to a ruby server.) This problem arises that I have to forward individual ports to the individual IP's of each of my special servers. But that's not how it is in the real world (each of my dedicateds has its own "DMZ'd" connections by the datacenter of course). So my router (Linksys WRT54g, flashed with DD-WRT) has only one IP allowed for DMZ. Is there a way to like make this IP go to a "subrouter" system on my Windows VMserver so that all the IP's they attain are DMZ style? I realize I'm probably making no sense here...hopefully some smart fellow on here understands.

router -> (DMZ'd IP) VMserver Windows computer -> IP's from VMserver go to VM's which gain DMZ access

Some of the SMC old Barricade Models can do 8-10 DMZs.

However, you need an external IP for each DMZ, you can not resolve multiple DMZs to a single external IP.

Try to find this one, SMC 2804WBRP-G Wireless Barricade.

I was hoping to go existing stuff.

And the reason I thought it was possible was because what I'm going for is all ports are available to all systems equally, just like on the LAN. On the LAN I cna access any port I want without forwarding. I can also play UT2004 at the same time bro does, meaning we are using the same port on the same external IP to play on the same game server. So it isn't possible to do this with all ports (since DMZ gives an IP all ports).

The reason you can play UT2004 or other programs (like Skype, eMule, etc) that needs port forwarding is that you have a UPNP router.

When you run a program, they will setup the forwarding ports for you automatically for different PCs. Not because you are on a LAN.

Check your DD-WRT flashed router, under Applications & Gaming tab, then UPNP, you will see application name, IP & ports entries automatically created by those applications. I use DD-WRT flashed ASUS router myself.

If you need multiple DMZs, you need multiple public IPs.

well this sucks...

But that's not how it is in the real world (each of my dedicateds has its own "DMZ'd" connections by the datacenter of course).

And in the real world where non-SOHO routers are used the term DMZ doesn't mean "all ports forwarded" either. In fact it means the exact opposite.

True the DMZ on a home router is different from a true secure DMZ setup.

I finally found a pic that describes what I mean.

Do i need multiple IP's for this?

Yes, as long as you want same port, same protocol.
