CentOS routing help
« on: December 21, 2010, 10:30:42 AM »

Good day, I have set obtained a /48 and succseffly set up the tunnel, my router can ping6 ipv6.google.com and I get a responce, I can also visit it on my browser. however my other host on my lan can ping only the directly connected interface and nothing else. Any help would be aprechiated. Below is the router set up

First, a couple things.

The IP on he-ipv6 should be 2001:470:b115::2 and your default route should point to 2001:470:b115::1

The IP you have on eth0 should be out of the /48 you grabbed.  

EDIT:

Same thing for eth1..take a /64 out of your /48 and assign an address out of that

Same thing for your lan host...take another /64 out of your /48 and assign an IP address out of that

Routed /48:    2001:470:b115::/48

the 2001:470:b115:: is my routable address space so using    2001:470:b115::X should be alright?

I am going to make the change noted above and let you know.

If that's what you say it is, so be it.

The problem is you're using that same network for your tunnel /64

Let me see if I can make this clearer...  Lets say 2001:db8:1:1::/64 is your tunnel /64 and 2001:db8:f::/48 is your routed /48.  The address on he-ipv6 should be 2001:db8:1:1::2 and the default route should point to 2001:db8:1:1::1  For eth0 on your tunnel machine, you would select a /64 out of your /48, say 2001:db8:f:1::/64 and assign an address, say 2001:db8:f:1::1.  Then, for eth1, you assign another, say 2001:db8:f:2::1  (assuming those are connected to different networks).  For eth0 on your host computer, you select another, say 2001:db8:f:3::1

Make sense?

What is your tunnel /64 that's listed on the webpage?

   Routed /64:    2001:470:1d:417::/64

so I made some changes to the script

modprobe ipv6
ip tunnel add he-ipv6 mode sit remote 216.66.38.58 local 75.152.109.214 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1d:417::2/64  dev he-ipv6
ip route add ::/0 dev he-ipv6
ip addr add 2001:470:b115::1:1/64 dev eth0
ip addr add 2001:470:b115::2:1/64 dev eth1
ip -f inet6 addr
sysctl -w net.ipv6.conf.all.forwarding=1

I think this right?
so on the host machine I would use say 2001:470:b115::3:1/64 dev eth0 ? and what about the next machine on the LAN i could use 2001:470:b115::3:2/64 ?

but eth1 and LAN machine are connected via a swith so they should be on the same network 2001:470:b115::2:2/64 ?

I am going to restart the router with the canges and see if anything works.

also how do i make the default route: 2001:db8:1:1::1  For eth0 on my tunnel machine?

You are hosting this tunnel on a PC, right?  (as opposed to a cisco router or something)

If eth1 and your lan machines are on the same network segment, then yes, they should have the same  /64.  One host could be 2001:470:b115::2:2, one could be 2001:470:b115::2:3, ect.  If you did that, 2001:470:b115::3:1 would be acceptable to use on eth0

I'm not sure what you mean by this

yes its a CentOS Linux box or well VM

and I ment how do I add the default route
ip -6 route add :: via 2001:470:1d:417::1/64 ?

So I canged the address and they are

eth0      Link encap:Ethernet  HWaddr 00:0C:29:FB:C0:CF 
          inet addr:75.152.109.214  Bcast:75.152.111.255  Mask:255.255.240.0

          RX bytes:48828 (47.6 KiB)  TX bytes:51682 (50.4 KiB)
          Interrupt:75 Base address:0x2080

he-ipv6   Link encap:IPv6-in-IPv4 
          inet6 addr: 2001:470:1d:417::2/64 Scope:Global
          inet6 addr: fe80::4b98:6dd6/128 Scope:Link
          UP POINTOPOINT RUNNING NOARP  MTU:1480  Metric:1

          TX packets:850 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:622887 (608.2 KiB)  TX bytes:231573 (226.1 KiB)

lo        Link encap:Local Loopback 
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host

          RX packets:2636 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0
          RX bytes:3861316 (3.6 MiB)  TX bytes:3861316 (3.6 MiB)

and LAN host is now 2001:470:b115::2:2/64 and it can ping 2001:470:b115::2:1 not a problem but not 2001:470:b115::1:1 I get destination unreachable address unreachable. If I try to ping the tunnel 2001:470:1d:417::2 I get Connect: Network unreachable.

Sorry for my ignorance, and thaks for the help

So if you do a "ping6 2001:470:1d:417::1" it doesn't work?  That's the other end of the tunnel, which means your runnel isn't up.  But, from the traffic statistics, it looks like traffic is being sent. (There's more traffic there than there is on eth1)

You're going to want to route your /48 out eth1.

As for your default route, take a look at this  (Which, if you don't have a default route, pings wouldn't be working)

this is what I get from the router

as for routing the /48

RTNETLINK answers: No route to host

I'm lost

Code: [Select]

That's your default route.

I've read that for some kernels, you need to add that route from the link before

ip route add 2000::/3 dev he-ipv6

Something strange is happening

Code: [Select]

According to that, I can ping your side of the tunnel, but not HE's side

I can even ping your eth1

Code: [Select]

[carl@mars ~]$ ping6  2001:470:b115::2:1
PING6(56=40+8+8 bytes) 2001:470:c27d:e000:20c:29ff:fe8a:1618 --> 2001:470:b115::2:1
