My real LAN uses 192.168.10.1 as gateway to the Internet.

For now I can only connect one of the two virtual boxes to my real
network, but not both. This is how I do it:

# kldload aio kqemu if_tap bridge
# sysctl net.link.ether.bridge_cfg=rl0,tap0
# sysctl net.link.ether.bridge.enable=1
# qemu-system-x86_64 -hda Win2k.img -m 512 -localtime \
  -net tap -net nic

When now I try to connect the second virtual box, it will steal the
first box's network connection.


i think you need two seperate tap interfaces:

qemu -hda Win2k.img ... -net tap,ifname=tap0

and

qemu -hda freebsd.img ... -net tap,ifname=tap1

but i'm not sure about the bridge configuration. my guess is you need
two seperate clusters (see bridge(4))

sysctl net.link.ether.bridge_cfg=rl0:1,tap0:1,rl0:2,tap1:2

No success yet :(
Only one of the two machines will be connected correctly.

Thanks anyway,

Uli.

 Hi!

 I am trying to connect two virtual Qemu boxes to my real
 network. This is what I would like to set up:

 Ah, yes: This is my /etc/qemu-ifup
   #!/bin/sh
   ifconfig ${1} 0.0.0.0

 Thanks for your help,

Connect the interfaces to a bridge interface, and connect that to the
external interface you want.  Sorry I can't give a full formula, but 
my lab configuration is down for, um, corporate restructuring.
