WRT54GS v1.1 / Tomato / IPv6 Questions

    I have installed Windows 7 Ultimate on several of my PC’s and I see that IPv6 is seems to be the preferred network protocol. I am running a Linksys WRT54GSv1.1 using a stock version of Tomato version 1.27 and was wondering if the router/firmware can handle IPv6 on the LAN side and if so, where in the routers firmware, I need to set it up.

    Also, with IPv4 it was easy to setup a device’s static IP address, once I setup my LAN’s network addressing scheme, with IPv6 it doesn’t seem to be that easy. Is there any way to translate what I have for IPv4 addresses to the new IPv6 address? In other words how do I take the routers IP address of and change it to an IPv6 address and a PC’s address of and convert it to IPv6?

    Thanks for any help you can provide.

    Tomato doesn't have IPV6 capabilty, but you can probably tunnel through it using IPV4 if you want to connect to something in the internet that is also IPV6.

    Does your ISP give you a bank of IPV6 addresses to use? The whole concept of nat-router is blown out of the water by IPV6, no nat needed or possible, no port forwarding etc, but you will need a firewall and an active directory because its not going to be easy to remember IPV6 IP addresses!

    dd-wrt has more IPV6 functionality enabled, but I'm not sure what that means.

    There is no reason to run IPv6 in your LAN or any LAN.

    If you do away with ipv4, there is a lot of reason to put ipv6 on your lan. It is nice to have a homogeneous network. IPv6 is coming whether we like it or not, the question is when.

    Windows 7 has features that require IPv6 - e.g., homegroup

    And as Lyme said, IPv6 is coming whether folks like it or not...and this may be the issue that motivates me to move to a different firmware.

    HomeGroup works fine under IPv4 or Teredo. This has been repeatedly verified, and Teredo will allow for reverse compatibility for a *LONG* time to come. IPv6 is "coming" as fast as it has been for more than a decade now. It will certainly be a part of the intranet long before the internet, but even then Microsoft has publicly admitted that trying to "force people's hands" with HomeGroups was a grave tactical error.

    All of that having been said...the biggest thing preventing HomeGroup from working properly on most installations is AVG, not a lack of IPv6 on the router. It is _NOT_ required.

    Pardon my ignorance but is IPv6 a software (firmware) function, hardware or a combination of both? Also, if you have a modem set in bridge mode does it need to have firmware/hardware support of IPv6 or is the information just passed through?

    It's a firmware function - specifically, the version of the Internet Protocol supported. A bit of Googling will return a (lot of) information on this, most of which can be considered rather obscure.
