IPv6

Hi,

My ISP just started supporting IPv6 and I have configured m0n0wall to get an IP address via DHCPv6 and a subnet via DHCP-PD.  That all works great.

However, there's no default route so I can't send any IPv6 traffic over the WAN.  I saw in the "what works in IPv6" post that it says "default route via slaac not working".  I guess this means I must somehow configure the default route manually, but how do I do this, and how do I figure out what it should be?

Thanks.

OK, I found this thread which was quite helpful, however I don't have it working quite yet.

I disabled forwarding with sysctl, then copied in rtsol (since it didn't seem to be included) and ran it:

$ chmod +x /tmp/rtsol; /tmp/rtsol -d sis1
checking if sis1 is ready...
sis1 is ready
send RS on sis1, whose state is 2
received RA from fe80::200:24ff:fec4:78f4 on an unexpected IF(sis0)
received RA from fe80::201:5cff:fe24:b6c1 on sis1, state is 2
OtherConfigFlag on sis1 is turned on
stop timer for sis1
there is no timer

sis0 is the LAN, sis1 is the WAN and the :7874 address is m0n0wall (I'm using rtadvd, no DHCP on the LAN), so that's fine. Does that mean the :b6c1 address should be the default route?  If so, I can't figure out how to add it, and rtsol doesn't seem to add a default route itself.

I also notice that I could have got the same information from the logs, since rtadvd was complaining:

Jun 18 07:11:29 plucky rtadvd[309]: <ra_input> received RA from fe80::201:5cff:fe24:b6c1 on non-advertising interface(sis1)

Help?

Thanks!

Are you using 1.8 beta ?

1.33 doesn't work right for PD and has this problem. 1.8beta has this fixed

No, I'm not. So there's no workaround for 1.33?

The patch to get this to work in freebsd8 (m0n0wall 1. doesn't back port to freebsd6 (1.33) , so i'm afraid, no and it's not a simple backport as there are some features in freebsd8 that are used to make this work correctly, they would have to be backported to.

Have you tried 1.8 ?

No, it'll be a few months until I can — I'm currently 1000 miles away from my box running m0n0wall and I already accidentally deleted my default route while trying to figure out a workaround.

Thanks for your work on IPv6; hopefully I'll be able to use it one of these days...

Just to close this up, I was able to install a 1.8 snapshot a few weeks ago and everything works great now.

Just curious about your setup. If you enable the Traffic Shaper does your IPv6 via DHCPv6-DHCP-PD still work?
