One dsl modem per VM ( 4 total )---with one nic?

[vb-newb]

Is it possible to use virtual box to run one dsl modem per VM ( 4 dsl's -- 4 VM's [ all win 7 ] -- 1 windows 7 box / AMD 6core / 12gb ram ) and just use the motherboard controller with a 4 port router to the dsl's?

Or do I need one nic---per VM---per dsl modem?

All wired. No wireless!

The reason I ask is each VM needs its own internet connection with control over the ip address as to be able to change it with a reset if needed.

Thanks in advance for any advice.

That cant work.

That cant work.

Why? Which part?

You might get it to work with (4) separate NICs or (4) separate USB Ethernet devices.
The trick is the host can not see the USB devices and since you will more than likely be using the exact pieces of either you will have a hard time keeping them straight.
Not sure that you could use the motherboard as a USB router though, better stick with individual one to one devices IMHO.
Interesting idea though. Let us know how it goes.

My original idea was to just run seperate low cost pc's for each modem but was hoping to save some dough by VM's on one multi-core super box.

So going by your opinion this can be done using "one-to-one" nic / modem setup?

I'm asking because I've never used virtual box or any VM software for that matter. This will be a whole new experience for me.

Any other yay's-or-nay's before I take the plunge?

Get a switch, configure each DSL modem to use a separate IP range and give the VMs static addresses. The DSL modems must NOT have DHCP enabled for the LAN side, else things can get messy.

Hey Sasquatch, would a Cisco Linksys RV016 Multi WAN VPN Router work? It can connect up to 7 internet connections.

Would this be able to take care of the DHCP automaticly without me having to mess around with the software?

Do I still have to run 4 nics in the server box or can I run just one cable through the motherboard nic to the wan router?

Thanks for your help.

As long as it can provide separate private subnets per WAN connection.

As I said, don't use DHCP on a shared line. Only if you have physically separated the network will it work.

You didn't understand my post. Read it again. It doesn't say you have to use multiple NICs on the Host, you just need a switch to hook up the DSL routers and your PC, and configure the Guests to have a static address in the range of the DSL router you want to use.
