I still get the same error,

cannot assign requested address.

One more question,

when I try to create a virtual interface in the VM,

auto eth0:0
iface eth0:0 inet6 static
address 2001:470:481c::1
netmask 48

i get an error:
STOCSIFFLAGS: Cannot assign requested address.

the address is the /48 assigned.

What could be the problem?

My windows machine has multiple ipv6 address, how do i remove the second one , coz it uses it to for ipv6. (attached jpeg).

If you want to use the ::4 address, tell the VM to not do RA

how do i do this? I'm still getting those addresses.

This is where you'd need your /48.

Simply pick a /64 for use on each interface (assuming you wanted the interfaces to be on different subnets/networks) and away you go.

WHere do we use the /48.

Is it possible to have multiple interfaces on the VM each in a different IPv6 network, and send the traffic through the tunnel outside?

Thanks a lot for your help. It is working.

Can I setup a Ipv6 LAN running on the VM and send traffic through the tunnel ?

I can ping ipv6.google.com.

The address shown is 2001:470:67:47:a00:27ff:fe89:7feb. My VM is getting that address, but the interfaces file has eth0 inet6 --> 2001:470:67:47::4

seuser@seuser-desktop:~$ ifconfig -a

what could be the issue?

hey thanks for the reply.


I am able to get to the internet through the vm but i cant ping the server tunnel endpoint: 2001:470:66:47::1; why is that?
I check the with testipv6.com; it passes all the tests however the ipv6 address shown differs from the static one i configured.

I m not sure about that.

Do you know where i can find information about that.

yes the tunnel works from the windows side.

I can ping the windows machine from the ubuntu vm but can't access the tunnel from the ubuntu vm.

What could be wrong?

My topology is as shown in the jpeg.


The default GW for the ubuntu VM is 138.111.56.12 and ipv6 2001:470:67:47::3

i am able to ping client side of the tunnel but not the server side of the tunnel, so cant get to the web.

everything is working perfectly on windows.

P.S. I have also attached the ip address config, please let me know where i went wrong.

Sorry. Here it is attached.

I can ping the ipv6 address on the windows machine from the VM, but can't access the internet.

I have configured the ipv6 addresses as shown in the attachment,

However, I am still not able to get to the internet from the VM.

Thanks.

I have assigned the Bridged LAN :
Ip address:  2001:470:67:47::3

What addresses do i assign to the ubuntu VM it is bridged, but can't get to the internet from the VM.

Server IPv4 Address:64.62.134.130

Client IPv6 Address:2001:470:66:47::2/64

I have assigned 2001:470:66:47::3/64 to my bridged LAN with defualt GW as 2001:470:66:47::1

For the Ubuntu VM, i have created a bridge. See attached the ubuntu address assigned.
