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:

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.
