Hi folks,
I'm setting up IPv6 at home. On the gateway, I can ping6 just fine. But
not from within the LAN.
I have:
Routed /48: 2001:470:8a86::/48
Routed /64: 2001:470:1f07:b80::/64
On the gateway, I have this:
# cat /etc/rtadvd.conf
fxp1:\
:addrs#1:addr="2001:470:1f07:b80::":prefixlen#64:tc=ether:
Where: fxp1 is on my internal LAN which has 2001:470:1f07:b80::1 as an
IP address. (you should be able to ping6 that).
Starting rtadvd I get:
# /usr/sbin/rtadvd -dDf -c /etc/rtadvd.conf fxp1
rtadvd[33958]: <getconfig> fxp1 isn't defined in the configuration file
or the configuration file doesn't exist. Treat it as default
So why that message? And is it the cause of the 'no route to host'
message below?
rtadvd[33958]: <ra_timer_update> RA timer on fxp1 is set to 16:0
rtadvd[33958]: <main> set timer to 15:998571. waiting for inputs or
timeout
rtadvd[33958]: <main> set timer to 0:4276. waiting for inputs or timeout
rtadvd[33958]: <ra_timeout> RA timer on fxp1 is expired
rtadvd[33958]: <ra_output> send RA on fxp1, # of waitings = 0
rtadvd[33958]: <ra_timer_update> RA timer on fxp1 is set to 16:0
rtadvd[33958]: <main> set timer to 16:0. waiting for inputs or timeout
rtadvd[33958]: <ra_input> RA received from 2001:470:1f07:b80::1 on fxp1
rtadvd[33958]: <main> set timer to 15:994315. waiting for inputs or

From a client on the LAN, I try this:
$ ping6 ipv6.google.com
ping6: UDP connect: No route to host
From the same client (where em0 is the nic)
$ netstat -nr -f inet6 | grep em0
fe80::%em0/64 link#1 U em0
fe80::21b:21ff:fe51:ab2d%em0 link#1 UHS lo0
ff01:1::/32 fe80::21b:21ff:fe51:ab2d%em0 U em0
ff02::%em0/32 fe80::21b:21ff:fe51:ab2d%em0 U em0
Can you see something I'm doing wrong?
I am now convinced the problem is rtadvd. Gateway and internal box are
both FreeBSd 8.1-stable.
After I issued this command on the server:
# route -n add -inet6 2001:470:1f07:b80::/64 -interface fxp1
add net 2001:470:1f07:b80::/64: gateway fxp1
And this one on the internal box:
$ sudo route add -inet6 default 2001:470:1f07:b80::1
Password:
add net default: gateway 2001:470:1f07:b80::1
I also did this on the client:
ifconfig em0 inet6 2001:470:1f07:b80::2/64 add
... things started working:
$ ping6 ipv6.google.com
PING6(56=40+8+8 bytes) 2001:470:1f07:b80::2 --> 2001:4860:800f::63
16 bytes from 2001:4860:800f::63, icmp_seq=0 hlim=57 time=23.466 ms
16 bytes from 2001:4860:800f::63, icmp_seq=1 hlim=57 time=23.221 ms
^C
--- ipv6.l.google.com ping6 statistics ---
2 packets transmitted, 2 packets received, 0.0% packet loss
round-trip min/avg/max/std-dev = 23.221/23.343/23.466/0.123 ms
Would you agree that rtadvd may be the issue?
