Glad to hear people are successfully using my IPv6 guide for Maxis.  Maxis seems to have increased their bandwidth to Singapore very recently so IPv6 speeds have greatly improved.  The end point of the tunnel is located in Singapore and HE has direct peering with Maxis it seems.

Interested to hear feedback and ways to improve the IPv6 guide to make it easier and more successful to follow.

As for why Maxis doesn't provide native IPv6?  I think it's a matter of cost.  Very few end users are requesting it while it would be expensive to reconfigure and test all of Maxis's routers and firewalls.  But since the IPv4 address range has been fully allocated, it is only a matter of time before IPS's like Maxis with provide native IPv6 addresses.  Double NATing is not a good long term solution.

If you are using the Singapore HE Tunnel broker address, then enter as is all the instructions except the parts with xxxx.  You only need to change the parts that have "xxxx:xxxx:xxxx:xxxx" to the IPv6 block your tunnel broker provides.  Have made that clearer in the instructions, thank you pointing that out.

Good question.  I just added:

"If at any point something goes wrong, simply turn off and on again your Maxis router and the changes will be removed, until you do the :saveall instruction at the end."

In addition, if for whatever reason, IPv6 stops working, all operating systems I've used fall back to using IPv4 instead until it starts working again without notifying the end user.

Have also added the suggestion of adding a backup before starting so the change can be reverted.

Finally, if everything goes really wrong, can always do a factory reset on the Maxis router and set it up again.

Hi, I have added a screen shot of telneting in.  Does it match what you are seeing?

It may also be because the user you are accessing the router with does not have permission to make these modifications.  If you PM me a screenshot I think I can work out what is going wrong.
