Routing Problem

lynxilein · February 21, 2009, 02:13:43 PM

Hello

I'm unable to get my gateway ready to route ipv6-adresses to my lan :(

On gateway ipv6 works perfekt:
gateway:~ # ping6 www.kame.net
PING www.kame.net(orange.kame.net) 56 data bytes
64 bytes from orange.kame.net: icmp_seq=1 ttl=52 time=149 ms
64 bytes from orange.kame.net: icmp_seq=2 ttl=52 time=160 ms
64 bytes from orange.kame.net: icmp_seq=3 ttl=52 time=151 ms

But on clients:
dell:~# ping6 www.kame.net
PING www.kame.net(orange.kame.net) 56 data bytes
From ipv6-test.highspeed-bone.eu.org icmp_seq=1 Destination unreachable: Not neighbour
From ipv6-test.highspeed-bone.eu.org icmp_seq=2 Destination unreachable: Not neighbour
From ipv6-test.highspeed-bone.eu.org icmp_seq=3 Destination unreachable: Not neighbour

Code Select


gateway:~ # ifconfig eth1 | grep inet6
          inet6 addr: 2001:470:1f15:12e1::2/64 Scope:Global
          inet6 addr: fe80::20b:6aff:fe80:f39d/64 Scope:Link
gateway:~ # ifconfig sixbone | grep inet6
          inet6 addr: 2001:470:1f14:12e1::2/128 Scope:Global
          inet6 addr: fe80::5cfa:cf14/128 Scope:Link
eth1 is my second lancard which is connected to a switch and routes my lan.

        {
                AdvOnLink on;
                AdvAutonomous on;
        };
};

I also enabled ip_forwarding in /proc for ipv6

I got a routed 2001:470:1f15:12e1::/64 and a 2001:470:d312::/48

Whats wrong?? :)

Any firewalls?
2001:470:1f14:12e1::2 is not pingable from the outside world.
and I would vote for 2001:470:1f14:12e1::2/64 insted of .../128

broquea · February 21, 2009, 03:23:00 PM

try using address ending ::1 on eth1, not ::2

and the tunnel interface, should try using /64 instead

and in radvd.conf:

Code Select

interface eth1 
{ 
        AdvSendAdvert on; 
        AdvHomeAgentFlag off; 
        MinRtrAdvInterval 30; 
        MaxRtrAdvInterval 100; 
        prefix 2001:470:1f15:12e1::/64 
        { 
                AdvOnLink on; 
                AdvAutonomous on; 
                AdvRouterAddr on; 
        }; 
};

grrrr got it :( the problem was that SuSe sets confusing firewall-rules
shutted down firewall - now it works, but I'm unable to find out which rule
is generating this error... :(

broquea · February 21, 2009, 04:24:38 PM

It could be some rule blocking protocol 41 under ipv4 iptables, or something in ip6tables configuration?
