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:
ping 213.33.197.1

On Dom0 I see:
tcpdump -i xen-br0
12:41:41.697372 IP 213.33.197.2 > 213.33.197.1: icmp 64: echo request seq 1
12:41:41.697709 IP 213.33.197.1 > 213.33.197.2: 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
                                                        vif2.0

Does your iptables FORWARD chain in dom0 prevent the forwarding of
packets across the bridge?

iptables has no any rules. Actualy, even stoping iptables does not help.
