Hi All,

I'm trying to setup a dhcpv6 server in my office with CentOS 6.1 + dhcpd6, below was the dhcpd6.conf file.

Code:
default-lease-time 600;
max-lease-time 7200;
log-facility local7;

authoritative;

subnet6 2222:1111:107a:7::/64 {
        range6 2222:1111:107a:7::500 2222:1111:107a:7::1000;
}

allow leasequery;
after i'm start the dhcpd6 service with the command:

Code:
/usr/sbin/dhcpd -6 -f -cf /etc/dhcp/dhcpd6.conf eth2
The service are successfully start with the info that show as below:

Code:
Internet Systems Consortium DHCP Server 4.1.1-P1

For info, please visit 
Not searching LDAP since ldap-server, ldap-port and ldap-base-dn were not specified in the config file
Wrote 0 leases to leases file.
Bound to *:547
Listening on Socket/5/eth2/2222:1111:107a:7::/64
Sending on   Socket/5/eth2/2222:1111:107a:7::/64
I'm trying to use a Win 7 machine and another CentOS 6.1 machine to get IPv6 address from the DHCPv6 server that I've setup but it fail to get any IPv6 address. By using wireshark to capture the packet, I only see the client try to send a DHCPv6 Solicitation to all DHCPv6 multicast group but DHCPv6 server never reply to the solicitation, anyone encounter similar issues? I've disabling the ip6tables to ensure is not firewall issues. Hope you guys can advise.

Cheers,
