6rd support added

databeestje

I'll have to look into that check and why it is triggering the private address check.

Strange.

You are right though, it should just work.

Do you need to see any additional log entries to help troubleshoot this? I started working on getting HE setup, but if 6rd 'should' work I'll clear all that config off so I can be ready to try something.

Well, I think I found why it detects my ip as 'private':
function is_private_ip($iptocheck) {
$isprivate = false;
$ip_private_list=array(
"10.0.0.0/8",
"172.16.0.0/12",
"192.168.0.0/16",
"99.0.0.0/8"
);
foreach($ip_private_list as $private) {
if(ip_in_subnet($iptocheck,$private)==true)
$isprivate = true;
}
return $isprivate;

This is located in pfsense-utils.inc. Rather odd. I'm going to upgrade to the latest snapshot, and then adjust that ip to see if 6rd works.

Removing the ip fixed the private ip issue (and Chris changed MASTER to remove the bad ip range), and the firewall now appears to auto-config the correct ips (as best as I can tell), ~~however I'm not getting a default route for some reason. I guess I'll fiddle with this some more over the weekend. Almost there.~~

EDIT: typing this in: route add -inet6 default 2602:300:c533:1510::
fixed my default route issue, once I put that in, everything (even PCs on the LAN) can ping ipv6 stuff. Yay!

So the major issue is fixed, with the private ip being detected wrongly… the minor issue, 6rd isn't auto-setting the default route properly.

Speed test comes back a bit slow, probably because I'm pulling from Calif, and I'm in the Louisville area.

Still trying to get this working, just fiddling with my pfSense settings at the moment.

Paste of the forum post below of their example Cisco config:

Hi,

If you have Cisco hardware capable of running a version of IOS that supports 6rd (minimum: 15.1(3)T) you will be able to add the following information to your config to get IPv6 connectivity.

This is provided 'as is' and at your own risk. No support will be offered by iiNet, nor will any responsibility be taken for unsecured networks resulting from adding this to your config.

It is your own responsibility to obtain the appropriate version of IOS and secure it appropriate. This will not be supported by iiNet.

6RD Configuration Settings
As part of Charter's IPv6 Trials we have made available a Public 6rd Border Relay. If you are interested in participating in our early trials and own a device that supports 6RD use this configuration information to begin experiencing the Next Generation Internet:

6rd Prefix = 2602:/32
Border Relay Address = 68.114.165.1
6rd prefix length = 32
IPv4 mask length = 0

Primary DNS Address = 2607:f428:1::5353:1
Secondary DNS Address = 2607:f428:2::5353:1

I have recent used Charter's 6RD setup and noticed a quirk on my side… My lan is setup as a TRACK for IPv6 and it does get an address and then each client gets an IPv6 address without issues from there. However I've noticed in my setup the IPv6 DNS server isn't coming across in windows. My DHCP server in PFSense (IPv4) is setup to send the IPv4 LAN address which is able to resolve IPv6 DNS servers but how do I allow my DHCP to send a IPv6 DNS server also?

How do you have DNS items configured in pfSense DHCP server page?

They are blank which would mean they inherit they are setup as the IPv4 LAN address. But in my case is the PFSense DHCPv4 actually issuing DHCP to my IPv6 clients or is Charter's 6RD platform?

I haven't tried it myself, but in Canada, Rogers offers this:

Provider Prefix Sites 32
Mask Bits 0
Relay Address 66.185.95.192

I guess i am a little too nooby to get all this,

My isp information is:
Altibox 6RD border relay: 213.167.115.92
15 bits prefix.

Can someone explain how this thing works, or is there an article i cant find on the wiki?

Please note that Swisscom will change the IP of its 6rd Border Relays to 193.5.29.1 at April 9th, 08:00. This change will be reflected in the DNS name 6rd.swisscom.com at the same time (plus some propagation time through DNS).

Altibox/Lyse, Norway
6RD IPv6 Prefix: 2a01:79c::/30
6RD Border Relay: 213.167.115.92
6RD IPv4 Prefix length: 0

Results in a /62.

They're using dhcp option 212 to distribute the configuration to the devices that support it.

I haven't managed to get it to work myself yet. It adds the correct address to the interface - the one I've been told I'm supposed to get - but I can't actually reach anything from it. Not entirely sure if the problem is on my end or with my ISP. Running Pfsense 2.1-RC0 (amd64) built on Tue Jun 4 20:54:59 EDT 2013.

Hi Nulani,

As far as I know 6RD has been broken in 2.1 since mid-January.

You can find some additional details in this post:

Some commits were made this week that others reported fixed the issue. Are you still seeing a problem on a current snapshot?

I'll update this weekend and see. It isn't working in June 4th.

Hi jimp,

I just gave the June 6th RC-0 build a try and if anything it was working even worse. Ordinarily I can reach the http://test-ipv6.com/ website and confirm that 6RD isn't working but with the RC-0 build I couldn't even do that.

This was with a straight update from Jan 18th to June 6th using the instructions in the sticky.

Rolling back the vm to my Jan 18th build got me right back up & running.

I've been keeping track of the ticket I opened for this: https://redmine.pfsense.org/issues/2882 so I was unaware of any change that had been made that might have fixed 6RD.

Should work with tomorrow's snapshot, my test system is working now.
