can u show how to do it?

this is my routing table:

Code:

[root@ip6 ~]# netstat -nr
Kernel IP routing table
Destination      Gateway                Genmask                Flags    MSS Window  irtt Iface
202.47.88.64    0.0.0.0                   255.255.255.240        U           0 0              0 eth0
172.27.11.0      0.0.0.0                   255.255.255.0            U           0 0              0 eth2
0.0.0.0              202.47.88.65         0.0.0.0                        UG         0 0              0 eth0

so, how i do create a route for that /48 on my routing table?

so i also need to assign /48 besides /64 in the router? is it something look like this code?

Code:

auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64
        address 2001:470:ec64::1
        netmask 48

this is my tunnel details:

Code:

Server IPv4 Address:216.218.221.42
Server IPv6 Address:2001:470:35:270::1/64
Client IPv4 Address:202.47.88.67
Client IPv6 Address:2001:470:35:270::2/6

Routed IPv6 Prefixes
Routed /64:2001:470:36:270::/64
Routed /48:2001:470:ec64::/48

The network which is only used with the connection between your endpoint and the servers at HE.
The conf are:

Code:

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.42 local 202.47.88.67 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:35:270::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

so,now i wanna make it as router that can connect multiple clients through wireless because as discussed here before that is also able to connect thru wireless (not only LAN) by using radvd.conf
radvd.conf:

Code:

interface eth0 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        prefix 2001:470:36:270::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

and the router and client are in different network, so as suggested by mr.cholzhauer i shud use prefix /48 for client interface:

Code:

auto wlan0
iface wlan0 inet6 static
        address 2001:470:ec64::2
        netmask 4

for the router:

Code:

auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64

#radvdump

^C
*error

and the client still cant connect to ipv6 site
client ifconfig:

Code:

i applied all ways those are discussed on this topic, shud revies from the prev discussion

regards
 

If your routable /64 isn't 2001:470:36:270, then you'll need to fix your radvd.conf and restart radvd.

what did u mean, doesn't it need to put the prefix that i got from HE 2001:470:36:270/64??

[2001:470:36:270]

now, the client get ip add from server, but i dont what exactly it is

so i conf wlan0:
auto wlan0
iface wlan0 inet6 static
        address 2001:470:ec64::2
        netmask 48

and conf radvdump for the server:
interface eth0 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        prefix 2001:470:36:270::/64 {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

and try a program to call radvdump

[root@ip6 ~]# radvdump

^C

still give the same error... :-(

in this case eth0 is the outside interface and eth2 is the inside interface?

so let say i've to conf eth0:
etc/sysconfig/network-scripts/init.ipv6-global
#server interface configuration
auto eth0
iface eth0 inet6 static
        address 2001:470:36:270::1
        netmask 64

*is it how to conf server?
and for client is wlan0 or what and how to conf it?

[2001:470:35:270::2/64]

yes, that my topology is.

you need to put the tunnel ::2 address on the outside interface of the router (and I think you already have)

is this what u mean?

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.218.221.42 local 202.47.88.67 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:35:270::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

what do u mean by inside and outside interface?

so u mean to conf each computer one by one without making one computer as a router for each clients through stateless conf?

how to assign it?can u show me the way? i dont really know how to do that?

hi guys, i need ur help

i got prefix /64 and /48 from HE, but i used /64:
2001:470:xx:xxx::/64

radvd conf:
interface eth2 {
        AdvSendAdvert on;
        MinRtrAdvInterval 3;
        prefix 2001:470:xx:xxx::/64 {

*doent give any response

and the client cant connect to the ipv6 yet? what shud i do?
is the connection between server and client false? thank u

so u mean i shud use eth1?

suppose my net shud be this way:

which interface that's advertising in the net? i still confused about eth0  and eth1

i got one nice tutorial
http://mirrors.bieringer.de/Linux+IPv6-HOWTO/hints-daemons-radvd.html

is it possible to implement through wirelss? because it is written there that it is useful for LAN network? why? what are different between simple conf, special 6to4 conf and debugging? do i need to do some ip calculation for each client?

why it always used prefix /64 while i have two /48 and /64?
