        Hi all,

I've got a problem with Xen Network Configuration.

I
want to create a Bridge between domU interfaces and a Dummy Interface
in dom0 and then route all traffic towards my wlan0 interface connected
to Internet.

Xen seems to configure all in this way but my domU is isolated from the rest of the network.

This is my domU Network configuration:
vif=['type=ioemu,bridge=xenbr0']

This is my xend-config.sxp:
(network-script 'network-bridge-dummy0 netdev=dummy0 bridge=xenbr0')
(vif-script vif-bridge)

This is my resultant dom0 ifconfig:

This is my dom0 bridge configuration:
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              vif0.0
                                                        pdummy0
                                                        vif1.0
xenbr2000               8000.000000000000       no

xenbr2000 is a bridge created by xend on start because it misread wlan0 configuration.


Could Anyone help me to resolve this situation?

If
I ping from dom0 to 10.0.0.2 I see (tcpdump) packets on all the bridge
interfaces, If I ping from domU to 10.0.0.1 I can't see any packet on
the bridge. 

TIA,
