Hello all,

I've got some strange problem with bridge. Ping from DomU doesn't
work, but I can see correct icmp packets on the bridge.
On domU I run:

On Dom0 I see:
tcpdump -i xen-br0
12:41:41.697372 IP > icmp 64: echo request seq 1
12:41:41.697709 IP > icmp 64: echo reply seq 1

I've spent 4 days playing with bridge, but no result! Please help me!
Fedora 3 and xen 2.0.6 are installed on my box.

Bridge config for dom0 is:
bridge name     bridge id               STP enabled     interfaces
xen-br0         8000.0004762663d3       no              eth0
Router config of Dom0 is:    *      U     0      0        0 xen-br0
default         UG    0      0        0 xen-br0

ip addr show (Dom0) is:
1: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:04:76:26:63:d3 brd ff:ff:ff:ff:ff:ff
    inet brd scope global eth0
3: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet brd scope host lo
4: xen-br0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
    link/ether 00:04:76:26:63:d3 brd ff:ff:ff:ff:ff:ff
    inet brd scope global xen-br0
6: vif2.0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
    link/ether fe:ff:ff:ff:ff:ff brd ff:ff:ff:ff:ff:ff

DomU has vif:
     (idx 0)
     (vif 0)
     (mac aa:10:00:00:00:11)
     (vifname vif2.0)
     (bridge xen-br0)
     (evtchn 12 4)
     (index 0)
