[Wylug-discuss] ipv4/6 broker and adsl supplier

[Kevin Barrass]

Ignore that the BT one is working now, just not the UKERNA one. Now to
figure out what I can do with the IPv6 address ;0)

Regards

Kev

Hi

I've tried both the BT and UKERNA tunnel broker to my Cisco router at
home using a /128 for testing and I cant get either working. Using the
BT stats page for the tunnel I can see my traffic hitting there tunnel
interface but not the other way around as below shows.

Does anyone know if Orange Broadband blocks this traffic as far as I
know its IP protocol 41.

The access list on my dialer/ADSL interface is allowing IP PROTO 41 from
213.121.24.85 so am damn sure its not my router that's the problem
possibly the crud from me to the Tunnel Broker ;0)

Any feedback appreciated.

Kev

Hi all,

following up Jim's talk, you can get a free ipv4 tunnel to the ipv6
network for playing with from home via BT: https://tb.ipv6.btexact.com/

It's free to sign up and use, and if you specify that you're using
Linux, they even e-mail you out pre-configured shell scripts.


Also, Black Cat Networks are one adsl supplier I know to offer direct
(non tunnelled) ipv6 connectivity:

http://www.blackcatnetworks.co.uk/services/adsl

I'm sure others exist and more will start cropping up.  I don't use
Black Cat for adsl myself, but do for some other services and they are
lovely.  I'm not affiliated with them in any way, although I do live
with some black cats.

As Jim said, before connecting up to the ipv6 network I'd recommend
brushing up on your ipv6 Netfilter skills (though with such a large
address space, at least you're far less likely to be randomly scanned by
script kiddies).

John.
