    Is there anyone who can provide some help on setting up IPV6 and Tomato builds with IPV6?

    Like to know how to setup LAN side with clients who can use IPV6.

    I can get clients to see a gateway, no IPV6 DNS. Can't get IPV6 printer to work.

    Stuff like that.

    Looked but mostly about WAN side getting IPV6 addresses for internet connection.

    All I know is that IF IPV6 is going to be the way of tomorrow they better be working on making it more plug and play.....

    Here's a guide for setting IPv6 up using an HE tunnel.

    There's an option "Enable Router Advertisements" that should automatically assign IPv6 address to devices that are IPv6 capable. If you want some ports opened on your IPv6 capable LAN device, so they are available from the internet, you'll have to open them in the router. This is found in "Port-forwarding --> Basic IPv6" I think I remember from another thread you wanting to enable access to your printer over the internet? This should be the way of doing it.

    "enable access to your printer over the internet?"

    Thanks but no. Just want to give it an IPV6 address over the LAN in the same way the router gives it an IPV4 address via the router's internal dhcp IPV4 server.

    Seems like it should be a simple thing but apparently not.

    Even when I enable IPV6 on relevant laptops they don't find the gateway nor the dns server when I enable IPV6 in the main router.

    In other words even when I enable DHCPV6 with address delegation that does not work in the same way as the DHCPV4. DHCPV4 hands out addresses to attached clients and gateway and dns information via the DHCPV4 server to LAN attached devices.

    How are you going about setting up IPv6? Through a tunnel? or natively through your ISP?

    Neither. I'm talking about handing out IPV6 addresses to LAN devices attached to the router. I have IPV6 capable LAN devices. Would like to use IPV6 across LAN. My ISP does not do IPV6.

    The bigger question is with IPV6 how do router LAN attached devices and the router handle IPV6 address information? Is it the same process as the DHCP server in the router now for IPV4? The router hands out addresses which the router than uses to manage the WAN side connection as its doing now with NAT? My understanding, and I have been reading the links, is that NAT is not required for IPV6. If so how do clients on the LAN side of the router connect to the WAN? How does the router keep track of those clients?

    Seems to me IPV4 on the LAN side is going to be around for awhile.

    If there is currently an IPV6 DHCP server in these Tomato versions how do we get LAN attached IPV6 enabled devices to obtain gateway/dns information and negotiate to the WAN and use IPV6?

    OK, I didn't know you wanted IPv6 only for your LAN, and not for an IPv6 enabled internet connection. I'm not sure the developers had your setup in mind when implementing IPv6.
    You perhaps could try the "Other (manual configuration)", manually assign your router some IPv6 address, and make sure router advertisements are enabled. If that works, you won't of course be able to access IPv6 web sites, nor confirm via the internet that IPv6 is working, but I imagine they would receive IPv6 address for local communication only. See if that works.

    "I'm not sure the developers had your setup in mind"

    Which developers? Tomato IPV6? Cause IPV6 has LAN devices in mind.

    The router already has an IPV6 address by the way.
