Resolved

Hello,

My ISP has just started testing IPv6. They have given me a new PPPoE account to use and some IPv6 address space-- a /56 and a /64. I have m0n0wall 1.3 with the WAN 'IPv6 mode' set to 'PPP'.

The initial thing I have found is that the IPv4 DNS servers (they are still working on IPv6 DNS) my ISP gives when logging in through PPPoE are not automatically added into m0n0wall as they were before (and still are if I turn off IPv6). m0n0wall is receiving them as you can see in the attached logs. If I manually add them under General Setup everything works again.

Another thing is the WAN's IPv6 Address is the link-local's address of my LAN interface. I assume this is how it is suppose to be set up since that happens automatically.

I'm not sure if I am setting this up properly at all (especially the addressing) and still have much reading to do but since I don't think very many providers are at this stage yet I would be happy to run tests or be of any other assistance I can be.

IPV6 is working on my other computers though and I can visit m0n0.ch and see my IPv6 address in the upper right.

Thanks

I use ipv6 via ppp from my provider, and get my dns as ipv4 addresses, but m0n0wall has no problem installing this automatically.  I'm not sure why your m0n0wall is having a problem, it's the same code used for ipv4 and ipv6 to do this.

as your WAN is a tunnel (pppoe) then that link local is correct for freebsd.

you have the /64 on the WAN interface and the /56 on the LAN I'm guessing, which is correct.

From you logs I see that RA is enabled on the WAN interface, you don't need this to be set, as your ip is configured via ppp.

Thanks for your reply brushedmoss. I've tried to do more reading... and learning!

The ISP seems to have the DNS working with the Windows PPPoE client and some other devices. I do have some VLAN's set up that I have not used in awhile, if 1.3.1 doesn't solve it I'll try resetting my config and trying from scratch.

You were correct in saying I did have RA checked on the WAN side. I didn't see much point in this but the text said "This option should normally be enabled." so not really knowing what I am doing I enabled it. Now that I have it disabled I periodically receive this in my logs "<ra_input> received RA from fe80::90:1a00:4243:14a8 on non-advertising interface(ng0)" is that my ISP sending me an RA?

It looks like nobody is using the /64. I have tried both the /64 and the /56 as the LAN address and they both worked fine. The WAN address always shows up as below which you said is correct, but I'm still trying to wrap my head around it and how it works.

Code:

WAN interface

PPPoE up 
MAC address 00:50:bf:90:77:ea
IPv4 address 206.248.185.4/255.255.255.255
IPv4 gateway 206.248.154.103 
IPv6 address fe80::213:21ff:feee:1c16%ng0/64
IPv6 gateway ng0 
ISP DNS servers 206.248.154.170
206.248.154.22

LAN interface

MAC address 00:13:21:ee:1c:16

IPv6 address fe80::213:21ff:feee:1c16%vr0/64
2607:f2c0:f00f:ce00::1/64

Code:

The last question, is it true RA only accept a /64 address? If so maybe a note should be made or a warning if the "Send IPv6 router advertisements" is enabled with anything but a /64 address.

Thanks again!

In the case of pppoe ipv6,  any packets sent to a destination not on your subnet, will head for the default gateway, which is the tunnel interface.  The Tunnel interface forwards these in ppp to the ppp endpoint which then routes them as normal.  your default gw doesn't have to be the next hop as you'd expect.

I will re phrase the text for RA on the WAN interface.

in 1.31 the text for RA already says

Using a number less than /64 will cause RA's not to be announced as there aren't enough subnet bits. i.e. /48

The /56 would normally be subnetted to /64's

Thanks for your explanations brushedmoss, they have helped a lot. Just as an update 1.3.1 didn't fix the DNS problem I described in this thread.

Do you know if it's normal to have the PRIDNS sometimes set to 0.0.0.0 as shown in the the initial logs (twice)? It then seems to to set the proper values twice.

e.g.

Mar  1 13:29:50 router mpd: [pppoe] IPCP: SendConfigReq #2
Mar  1 13:29:50 router mpd:  IPADDR 0.0.0.0
Mar  1 13:29:50 router mpd:  PRIDNS 0.0.0.0
Mar  1 13:29:50 router mpd:  SECDNS 0.0.0.0

I didn't find a bug to fix this :-)

what does you log show for ppp when ipv6 is disabled and dns from your ISP works ?

Thanks for keep trying to look into this! Sorry I always take so long to reply, it's my mom's house this is set up in and if I break something and can't VPN in...

I have just tried totally disabling IPv6 under "Advanced" and removing the DNS server under "General Setup". Which results in the following log:

Regardless of what it says it is not using the nameserver 206.248.154.22 or 206.248.154.170 once IPv6 is turned on. One of the changes I can see is both set of logs have "no servers found in /etc/resolv.conf, will retry" but the IPv6 has that at the very end when the IPv4 only logs has it earlier followed by the "using nameserver 206.248.154.22#53".

I'm open to trying anything else you would like and thanks once again.

Have a great day!

from /exec.php can you execute

cat /var/etc/nameservers.conf

Sure, here is the output:

Code:

$ cat /var/etc/nameservers.conf
cat: /var/etc/nameservers.conf: No such file or directory

This is /etc/resolv.conf

Code:

$ cat /etc/resolv.conf
domain lan
nameserver 206.248.154.22
nameserver 206.248.154.170

Both are with IPv6 enabled (and the DNS manually configured under General Setup).

can u give me that output with no dns configured and the override setting enabled ?

the pppoe client should put it's dns servers into nameservers.conf, which m0n0wall moves into resolv.conf, which dnsmasq picks up.

I should be much faster responding from now on! 

After deleting the DNS entries and leaving the override check this is what the logs showed:

Code:

And the outputs with exec.php

Code:

$ cat /etc/hosts
127.0.0.1 localhost localhost.lan
10.0.0.1 router.lan router
10.0.0.2 pbx.lan pbx
10.0.0.1 router.lan router

$ cat /etc/resolv.conf
domain lan

$ cat /var/etc/nameservers.conf
cat: /var/etc/nameservers.conf: No such file or directory

Here is the outputs after a restart (with no DNS manually configured, overrides allowed)

Code:

$ cat /var/etc/nameservers.conf
cat: /var/etc/nameservers.conf: No such file or directory

$ cat /etc/resolv.conf
domain lan

I noticed this in the logs---- when dnsmasq starts the PPP link isn't up yet and dnsmasq doesn't log anything else once the link does go up.

Thanks,  I need to figure out why you don't have a nameservers.conf

MK and I swapped some mails on this today, he pointed to a possible race condition.

try this;

goto /exec.php and upload this file

then copy it over the original  by executing

Code:

cp /tmp/ppp-linkup.txt /usr/local/sbin/ppp-linkup

then change the permissions by executing

Code:

chmod a+rx /usr/local/sbin/ppp-linkup

then goto wan and hit save, it should restart pppoe and hopefully fix the problem

Aha! After the changes:

Code:

$ cat /var/etc/nameservers.conf
206.248.154.170
206.248.154.22

So that did it! Will these changes survive a restart?

Thanks for working on it!

It won't survive a restart,  you need to wait until there is a new image, 1.32 which I hope will be real soon.
