Explorer test - web browser not seeing ipv6

[cholzhauer]

Yeah, EOL is usually bad ;)

Seems like everyone has been trying to use Vista/Windows lately for this, must be an epidemic or something

I take it you've ran the commands off the website

Code Select Expand


netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 123.456.789.011 123.456.789.012
netsh interface ipv6 add address IP6Tunnel 2001:db8:1234::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:db8:1234::1


And customized it for your own needs  (make sure if you're behind NAT, and I think you are, that you use the NAT'd address on your windows machine)

Make sure your firewall is passing protocol 41 (you might need to move your host to the DMZ or equivalent)  You'll need to use Wireshark or something to sniff the traffic and see what's going on.  Like you said, the linux machine would be better/easier because it is your router and is connected to every part of your network.

Well with the media running around telling people that the sky is falling, we're having to get our skates on.

yes, did all that. (10 times)

Yes... that's about the point where I think I'm going to bow out of trying to tunnel to this pc...

Yip...

but just to add to my fun radvd isn't installed on my Centos4 box and the repos have now gone... so how I'm going to get it and iptables6 is an issue...

I know I'm going to have to upgrade the fw eventually... but I've been putting that off...

See how we go.

Cheers for the help.

Good luck.

My plug is FreeBSD...fast, free, and easy to spin up in a VM if need be

[thinkdesignprint]

Good luck.

Thanks :)

easy to spin up in a VM if need be

Thought about that and then realized without protocol41 routing it won't be much help.

I've got debian5 vm running on my laptop all the time now.

Ok getting there...

choose linux-route2 instructions...

not sure I understand them but pasted anyway...

ip -f inet6 addr gave me output that I don't understand.

I can ping my IP - 2001:470:c:8e3::2 but I can't ping the gateway 2001:470:c:8e3::1 and I can't ping my VPS:  2403:cc00:1000:0:200:20ff:fe01:8502

Not sure what I'm doing wrong.  Suggestions?

Cheers Don

VPS = Virtual private server?  Not sure what that is

And what's with the 2403 address?

You still need a IPv6 address on eth0 

I dunno what your routed /64 is, but it's probably something like

ip addr add 2001:470:c:8e2::2/64 dev eth0

Did I grab the wrong address to show you...  I don't understand what the Scope stuff means yet.

Ok that makes sense...

There's the commands I've issued again...

Haven't I now allocated :2 in two places?
ip addr add 2001:470:c:8e3::2/64 dev he-ipv6
ip addr add 2001:470:c:8e2::2/64 dev eth0

Sorry, I know my linux routing skills here are lacking...  I do appreciate your patients with me.  I feel like a right knob right now :)

Review your tunnel's details page and you'll see the difference between the tunnel /64 and routed, and in BOLD

I refuse to use big red <BLINK> tags

[patrickdk]

2403:: is valid, it's allocated from APNIC's 2400::/12

inet6num:       2403:CC00:1000::/36
netname:        GPLHOST

Ok.  Sorry, all I did was follow the suggested install stuff.  I confess I just don't understand enough about this stuff yet.  With ipv4 I don't route, I just nat stuff about, and only in a small way.  I can see that this v6 stuff is going to require more understanding about routing.

I think I follow...

I've assigned the wrong IP to eth0


ip addr add 2001:470:c:8e2::2/64 dev eth0

should have been...

ip addr add 2001:470:d:8e3::2 dev eth0

Yes?

Now do I reasign it?  Do have have to remove the address or will it just over write it?

Do you have any recommended reading so I don't ask so many idiot questions?

Cheers Don

Sorry, I had never heard of that before.

You need to delete the first address...I assume the syntax is something like

ip addr delete 2001:470:c:8e2::2/64 dev eth0
ip addr add 2001:470:c:8e3::2/64 dev eth0


Some of the things in here might help

http://ipv6.he.net/presentations.php

[thinkdesignprint]

Thanks for your help guys... fixed it :)

See: http://www.bowenvale.co.nz/ipv6/ and http://www.bowenvale.co.nz/ipv6/?p=10

Got it all working in the end...

Quick summary:

    * Both ends of the 6to4 tunnel need to have a public IPv4 address
      (thought I guess you can probably do some dodgy NAT if you're
      forwarding protocol 41).
    * You only need to run one tunnel from one device on your LAN to HE.
      After that you route a /48 to you to get other things connected.
    * Protocol 41 needs to be allowed, and needs to be near the top of your
      firewall chain, not at the bottom :)
    * You need to tell HE your correct IPv4 end point.
    * You need to get a /48 routed to you by HE and assign a /64 out of
      that to your LAN.
    * You need to turn on ipv6 forwarding – echo "1"
      > >/proc/sys/net/ipv6/conf/all/forwarding.
    * Keep things simple. Use static addressing to start with, then maybe
      look at Radvd or DHCPv6.

Hopefully this could save someone a few dramas in the future.
