6rd on Telia, routing and RA

Okay, one last thing.

It seems that a save-apply on the wan interface actually fixes everything except for the default gateway. However, the lan interface keeps the old IPv6 address even though the wan interface acquired a new address, and my guess is that's the reason I can't get the traffic to flow. It acquires the new address as well but it seems to continue to use the old IPv6 address as source.

okay okay, one OTHER last thing. :)

I was right in my last post. When I manually removed the old IPv6 address from the LAN interface everything started working. So, from the top:

Reboot. This brings us to a point where the 6RD interface is up, and sometimes RA on the LAN works and sometimes not.
Save-apply on the wan interface. This fixes RA on the LAN, but the wan interface gets a new IP.
Add default IPv6 gateway on the pfsense server. Default gateway always seems to be missing, save-apply or not.
Remove the old IPv6 address from the LAN interface. Everything works, double rainbows all around!

how is your wan setup? dhcp? pppoe?

I don't have a pppoe setup where I can easily test.

I'm currently making due with my backup Huawei USB 3G modem (ppp) while urging the telco guys to please finish installing my new fiber…

I've been running for a few hours now after doing the manual steps I outlined above (save-apply the wan config to kickstart RA, manually creating a default route and removing the old IPv6 address from the lan nic), and everything seems to work perfectly.

I'm sorry, but I have not gotten round to it yet. It's not forgotten.

I'm sure I have a VM somewhere I can use for testing that will help. Nothing on pppoe yet though.
Willing to give me access?

I filled in your info, but the Telia relay isn't open for the world. Which is good.

On the LAN interface, it's set for track interface, prefix id 0.

On the WAN interface I selected 6rd, and the Telia information just as you did.

The WAN ipv4 address is DHCP and doesn't change really. I do see a default route.
default 2001:2002:d9d1:e4a6:: UGS 0 8 1280 stf0

And a radvd too.
root 49889 0.0 0.6 5860 1460 ?? Ss 4:27PM 0:00.01 /usr/local/sbin/radvd -C /var/etc/radvd.conf -m syslog

If my hunch is correct you can probably ping 2001:2002:5be3:1b48::1

Edit: Just verified it comes up with a default route for me on cold boot with a DHCP wan.

So, could it be related to the Huawei 3G, that the connection takes too long? Perhaps we should wait until I get my permanent connection installed and see if the problem solves itself?

databeestje · May 25, 2012, 4:00 PM

I wasn't aware you had a 3G connection, I sort of reasoned it was a PPPoE.

I'll have a go and test this on my 3G stick here.

databeestje · May 26, 2012, 8:15 AM

I tested with the Charter 6rd relay and even on the 3g stick it came straight up with a default route and advertisements. Need more looking.

Got my fiber installed today, finally. 6RD worked like a charm, so obviously my problems were related to PPP for some reason. I'm happy, but if you'd like to continue to pursue this and need any more data from me, just let me know.

Thanks.
