RADVD + IPV6 = Stuck...

[TimothyS]

I can't get my server to correctly forward IPv6 traffic. I have done everything that I possible can understand. I have literally been trying to figure this out for over 24 straight hours. Help would be greatly appreciated. This really is my last option, I don't tend to rely on the community too much. Thank you kind souls ;]

once again I appreciate all of your help.

Did you enable ipv6 packet forwarding in sysctl or proc?

[gudboy1]

i've the same problem, i even enable sysctl -w net.ipv6.conf.all.forwarding=1

it advertised the ipv6 to the client:

My bad, whatever you think your doing to add an IPv6 address to eth0 isn't working, it should be in "b" and instead its in "a":

Code Select Expand

eth0      Link encap:Ethernet  HWaddr 00:14:d1:20:51:98
          inet addr:192.0.254.140  Bcast:192.0.254.255  Mask:255.255.255.0
          inet6 addr: fe80::214:d1ff:fe20:5198/64 Scope:Link
          inet6 addr: 2001:470:a:xxx::1/64 Scope:Global

[TimothyS]

That is what I thought as well, but I do not know how to go about changing it in the configuration to see it reflect on ifconfig.

[broquea]

The quick fix is:

ip addr del 2001:470:a:xxx::1/64 dev eth0
ip addr add 2001:470:b:xxx::1/64 dev eth0

Thanks mate! That was exactly what I was looking for!
