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!

Does your iptables FORWARD chain in dom0 prevent the forwarding of packets across the bridge? James Kir wrote:> Hello all, > > I''ve got some strange problem with bridge.
