Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

There is no DHCP for IPv6.
Which part of that you do not understand?

You indeed do not need a DHCPd for IPv6, as it features auto configuration.
Your router just has to advertise itself properly on the LAN.


Anyways, there IS a dhcpv6 server and client, and it possible to use that.
Given you have a RedHat based system, following configuration should work:

/etc/sysconfig/network-scripts/ifup-eth0
IPV6INIT=yes
DHCPV6C=yes

/etc/sysconfig/network
NETWORKING_IPV6=yes

Oh, and beware that there is a bug in RH:
If the IPv4 address is static or not specified at all (means no DHCP), it will not start the IPv6 dhcp6c either. It's both or none.

You'd need to edit /etc/sysconfig/networking-scripts/ifup-eth to fix that

If you still want a dhcpv6 server, check this howto:

Works fine here. I did test that in a virtual centos 5.2 machine.

You may need a 4to6 tunnel, I use http://www.sixxs.net/ at home.

Not sure if it matters, but do you have a real IPv6 address?
