hello, the topology is like this:

centos v0:eth1 <------> centos v0: eth2 fc00:2:3:4::1 fc00:2:3::4

i turned the packet forwarding

If you are talking about forwarding on Centos V0, forwarding will have no effect here. You appear to be trying to ping eth1 from a box somewhere on eth2's network. This is still classed as an input to V0 and will be handled by the INPUT chain.

...

ping6 -i eth2 fc00:2:3:4::1 the output is

PING fc00:2:3:4::1(fc00:2:3:4::1) from fc00:2:3::5 eth2: 56 data bytes

...

From fc00:2:3::4 icmp_seq=1 Destination unreachable: Administratively

prohibited

...

From fc00:2:3::4 icmp_seq=2 Destination unreachable: Administratively

prohibited

...

From fc00:2:3::4 icmp_seq=3 Destination unreachable: Administratively

prohibited

...

From fc00:2:3::4 icmp_seq=4 Destination unreachable: Administratively

prohibited

Administratively prohibited looks like a firewall issue. Check your IPv6 firewall settings on V0

Thanks, it is truely because firewall issue. It's ok when i turned ip6tables stoped. Thank you all the same

...

why the box do not forwarding icmp packets to eth2? and how to set forwarding rules on centos 6.3? Thanks _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
