Hi,

i created two containers:

centos1 (ip 10.0.3.2)
centos2 (ip 10.0.3.3)

on this machine, i have created a bridge "lxcbr0" (Adress:10.0.3.1   
Bcast:10.0.3.255  Mask:255.255.255.0) with dnsmasq deamon attached on this  
interface.

/etc/dnsmasq.conf:

listen-address=10.0.3.1
bind-interfaces
dhcp-range=lxcbr0,10.0.3.2,10.0.3.5,12h
dhcp-option=3,10.0.3.1

-------------------------------

centos1 ping lxcbr0  -> works
centos2 ping lxcbr0  -> works
centos1 ping centos2 -> works

ping 192.168.2.1 -> doesn't work, why?

routes of the host machine:

Ziel            Router          Genmask         Flags Metric Ref    Use  
Iface
10.0.3.0        0.0.0.0         255.255.255.0   U     0      0        0  
lxcbr0
192.168.0.0     0.0.0.0         255.255.252.0   U     0      0        0  
eth0


and routes of centos1:


Ziel            Router          Genmask         Flags Metric Ref    Use  
Iface
10.0.3.0        0.0.0.0         255.255.255.0   U     0      0        0  
eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     1002   0        0  
eth0
0.0.0.0         10.0.3.1        0.0.0.0         UG    0      0        0  
eth0


What do i do wrong?
