hello, the topology is like this:
CentOS v0:eth1 <------> CentOS v0: eth2
i turned the packet forwarding
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 prohibited prohibited prohibited prohibited
why the box do not forwarding icmp packets to eth2?
and how to set forwarding rules on CentOS 6.3?
