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
Router config of Dom0 is:
213.33.197.0 * 255.255.255.192 U 0 0 0 xen-br0
default 213.33.197.1 0.0.0.0 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

DomU has vif:

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.
