Problems with Tunnel (can anyone help??)

[dwalker85]

Hi Everyone,

I'm having problems trying to get the tunnel to work, here is my attempts;

When i could not get the tunnel working i tried gogo6 client at http://www.gogo6.com/freenet6

It setup with no problems & used IPv6-in-UDP-IPv4 Tunnel (NAT Traversal)

I could not tell if my router supports protocol 41

My Tunnel Details;

IPv6 Tunnel Endpoints
Server IPv4 Address:216.66.80.26
Server IPv6 Address:2001:470:1f08:8d1::1/64
Client IPv4 Address:176.24.194.38
Client IPv6 Address:2001:470:1f08:8d1::2/64
Routed IPv6 Prefixes
Routed /64:2001:470:1f09:8d1::/64

I first ran the following on my pc (Winxp)

Code Select Expand

ipv6 install
ipv6 rtu ::/0 2/::216.66.80.26 pub
ipv6 adu 2/2001:470:1f08:8d1::2

Then i tried

Code Select Expand

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.0.5 216.66.80.26
netsh interface ipv6 add address IP6Tunnel 2001:470:1f08:8d1::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f08:8d1::1

After that i tried

Code Select Expand

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.0.5 216.66.80.26
netsh interface ipv6 add address IP6Tunnel 2001:470:1f08:8d1::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f08:8d1::1
netsh interface ipv6>add route 2001:470:1f09:8d1::/64 Local Area Connection publish=yes

I then ran show route

Then i tried to ping ipv6.google.com it said timed out or unreachable

Code Select Expand

I then fired up GoGo Client running as IPv6-in-UDP-IPv4 Tunnel (NAT Traversal) as tried to ping ipv6.google.com again

Code Select Expand

It works with GoGo client without any router changes

I would like to try & get the he tunnel to work if possible

Can anyone possibly help me please??

Thanks in advance

Where are you telling the device that does your IPv4 NAT to deliver the protocol 41 packets to your machine ending in ".5"?

[dwalker85]

I am entering 192.168.0.5 in the DMZ of my router but it does not seem to make any difference

Sometimes, depending on the router, that doesn't do anything.

You should fire up something like wireshark and look to see what's happening when your tunnel isn't working.  If you don't see return proto41 packets, you'll know that's your issue.

What router do you have?

[dwalker85]

Hi cholzhauer,

My router is a sky sr1001 (sky uk broadcaster/broadband provider)

I have wireshank installed how will i know what are the proto41 packets?

David

[cholzhauer]

Does this help?

[dwalker85]

Thanks cholzhauer,

Will now run wireshark & let you know the outcome

David

[dwalker85]

I have run wireshark with ip6 tunnel & see this message often;

icmp  Destination unreachable (port unreachable)

I do not see any thing about protocol 41

So does this mean my router does not support Protocol 41 or is there any more tests i could run.

Could i forward the port(s) for the tunnel to get round the problem??

David

[cholzhauer]

Remember, port =! protocol...forwarding ports won't help anything.

You should be seeing some protocol41 traffic...you should be seeing the traffic generated by your computer.  I have to assume that your router doesn't support protocol41, but I can't say for sure.

Why don't you try with an OS that isn't ten years old?

[dwalker85]

Hi,

Thanks Cholzhauer,

I did see traffic generated by my computer, but i did not see anything saying protocol 41 or IP6Tunnel

My 2 pc's are still running windows xp (yes i know it is obsolete & old) , so i would say my router does not support protocol 41 (the router was only released Jan 2013)

That would explain why IPv6-in-UDP-IPv4 Tunnel (NAT Traversal) from gogo6 works as it does not rely on the  router supporting protocol 41, but works on udp ports i think??
