I honestly feel like the old dog trying to learn new tricks.

can some one please explain what ipv6 address i should use for my lan interface if my wan ipv6 addy is 2610:xxx:xxxx:x::2/128 This is if i try to use static like in the SixXS wiki for m0n0wall.

or if i use DHCP-PD what shoudl i set my IPv6 Prefix Delegation at?


if there is a book ipv6 for dummies or a book that will explain ipv6 addressing so an slow person could understand I would appreciat knowing about it.

If your WAN address is a /128 address, then you will need another subnet to use for your LAN.  A major difference in IPv6 over IPv4 is that NAT is not intended to be used with IPv6 (there are so many addresses available, it isn't necessary). 

If you're using SixXS, you should be able to request a subnet that you can use on your LAN.  SixXS will most likely give you a /48 subnet, which is huge.

A good start for IPv6 info is the main wikipedia page:  and also the IPv6 Addressing page:

Thanks, I thought that might be the case.
Sixxs assigned me a /64 but the auto assign when
I set up m0n0wall gives me a /128.

I will work on this tomarrow, when I get it fixed I am still unsure
How to set up the LAN side.

Thanks again

If you have just a tunnel from Sixxs, yes it will be a /64.  That doesn't mean you can use all of those addresses however.  See the following from their site:

Basically, the /64 you have now is just used for the tunnel.  If you want multiple hosts, you'll have to request a subnet.  When you get your subnet, use the first address as the LAN address.  I would also suggest enabling Router Advertisements.

Thanks a lot for the help and information, The sixxs point program kind of sucks, I am wondering if I should have used one of the other services, but I will leave the server hooked up for a week and then maybe they will talk to me about a subnet.

Whats really interesting is that my isp could set me up on ipv6 but I have not found the right person to talk to about it, yet.
 I got to say though I am having a blast digging around this and learning something new.

There is only one book I would recommend

I only recommend this as I prefer to read books that are a practical guide and focussed on real scenarios, as I learn better from these books.  So if you have a good foundation of ipv4 , this might be the book for you.
