Everyone where I live is fed up of me grabbing their PCs to run Knoppix CD on them to do my linux network programming experiments on.

I thought why not use the embedded version of DSL to run multiple copies direct from the Windows desktop on a single machine.

If I run one copy it works flawlessly even though it sets the IP as 10.0.2.15 and even though my real IP is 192.168.1.14 it accesses the Internet.

What I want to do is run multiple copies and have them talk to each other but when I start a 2nd copy running on the desktop it gets the same IP address. So I change the IP to 10.0.2.16 using the windows tool, but after doing sudo su I cannot ping the first copy.

Is there any way to do this? What am I missing?

Argh! Who moved my post from the networking forum to the embeded forum, I'm sure it's more a networking issue than an embedded one  :(

afaik qemu just accesses the network like any other app, the "ip" you see is fake.

So this depends on how your network is set up.
If this machine is set up as the host router, I think you can use pseudo network interface tunnels for each connection.

EDIT: just saw your last post, but my post should answer it

if I was on knoppix and it was using a fake IP through NAT i would just go to iptables and turn it off....

but if I go to iptables it's not installed so how is DSL embedded doing the Network Address Translation to get the internet working?

I also tried setting the IP to same as my internal network on 192.168.1.x but all that happened is I lost the internet connection  ???  so it is NATing 10.0.2.15 somewhere...

Qemu is providing the network bridge. Qemu provides a DHCP server for such. DSL is only requesting an IP via its pump command.

You should check the Qemu site for Qemu's tun/tap networking support.
