IPv6 only on LAN
-
What would be the point of ipv6 if just internal.. At a loss to the point of that sort of setup..
"Generally speaking I suggest to avoid IPv6 tunnel provider. Native v6 connection from provider is the way to go."
I would suggest the complete opposite of this - Tunnel is the much more stable way to go, there are few if any ISP that really have their shit together for native ipv6. But tunnel is very easy to setup and stable as stable can be..
If you want to play with IPv6 and your isp does not provide it or not yet really workable/stable then get a tunnel.. If its not global ipv6 connected to the rest of the world I really don't see a point of setting it up internally.

I suspect you refer to the US. For Germany I would not concur. There are even ISP who actually do IPv6 better than lPv4 (CGN). I myself utilize a provider that hands me a static /48 prefix which is excellent. Our direct neighbor Belgium for example also does it quite well.
What is so shitty about YOUR native IPv6 connectivity? ;-)
Schaumburg is a funny city name btw :o -

ok, so you advise me to better implement IPv6 on the wan, right?
I was planning to deploy it first on my LAN just because I want to learn and though it would be better to start on my LAN, but from your comments it's probably better to start it on the wan interfaces.
Ok, I have two wan interfaces and I'm sure that will make things a little more difficult, any advise on IPv6 on multiwan?

Do you have the access point running as a bridge or is it acting as a router? I strongly suggest to use it as a bridge instead of a router.
Yes, but I cannot see how to switch the wdr3600 to "bridge" mode, I can only just set it up as an AP and don't use the WAN. I think this is not the same, do you think that can bring me some problems?
-
With consumer routers, you just use the LAN side and don't connect through the WAN port.
-
More specifically you follow this wiki entry to turn your wireless router into a bridged access point:
https://doc.pfsense.org/index.php/Use_an_existing_wireless_router_with_pfSense
This method works with just about every wireless router because they bridge the WLAN with the LAN ports on the device and you use one of the LAN ports as the "WAN" connection instead of the port that is normally used as the WAN on the router.

When I understand you correctly you have your access point already in bridged mode, which is fine. You can check if the router's LAN IP is in the same subnet as your clients are and your client's default gateway is the pfSense box and not the AP's IP.
Check which provider offers the better v6 support.
Start IPv6 only with that one provider. I suggest not to try IPv6 on both WAN interfaces at the same time.Just go ahead and enable IPv6 for one WAN interface of your pfsense router and then also enable Router Advertisement for your LAN. That should generally be it.
Some IPv6 configuration parameters look a bit overwhelming at first but don't stop to try. Also: read a lot about IPv6. -

Yeah that would be fantastic if you could get ISPs in the US to do that.. But this is not the case.. Here in the use your lucky to get a /60 and it quite often changes when the wind blows… So its like impossible to keep the same network address space.. I really don't get why they won't just give you a /60, /56 or /48 if you want and always hand you the same one.
Does your isp allow you to set the PTR records for this address space - HE does when you get a tunnel from them.
But just because your isp provides you good ipv6, why would you tell him to avoid tunnel if his isp doesn't provide him any ipv6 at all or its crappy. There are some that will only give you 1 /64, etc.
As to using any wifi router as just AP.. Yeah any wifi router can do that - just use lan, turn off its dhcp server - give its lan an IP on your network = AP..

Yes, I though it was right and verified that I have everything as the docs says about using a router with pfSense, so I'm right with that.
But I have one question, do I have to "setup something" for IPv6 on my router or everything must be done on the pfSense box it's "transparent" for the router?

Thanks everybody!

Actually, the DHCP server doesn't have to be turned off. There's nothing wrong with having multiple DHCP servers on a network and is often done on larger networks. You just have to ensure that duplicate addresses are not issued, but that can be done by simply having the servers hand out different portions of the address block. Also, these days, gratuitous ARP requests are often used to ensure duplicates don't occur.

Does your isp allow you to set the PTR records for this address space - HE does when you get a tunnel from them.
That's the only thing I'm not happy about. My provider has generated PTR for the whole prefix but I cannot request to set a specific PTR. For most purposes those generic PTR records suffice. You are right. The HE features are great. I used to run such a tunnel for over a year until I got my native connection.
But just because your isp provides you good ipv6, why would you tell him to avoid tunnel if his isp doesn't provide him any ipv6 at all or its crappy. There are some that will only give you 1 /64, etc.
All I was saying is that native IPv6 is generally a better idea than a tunnel. I don't presume that native IPv6 ALWAYS is better. This seems to be one of those exceptions.
It's really sad that your provider just fuxxxs IPv6 up :-( I would write a letter to customer satisfaction.
Anyhow I think even a dynamic IPv6 prefix is something you can work with. If I had to deal with a dynamic prefix I would update the changing IPs into valid DNS names. That can be done with pfSense by using DDNS. That way pfSense automatically updates the A record for a host if the IP changes.
I'm referring to: Services - DHCPv6 Server & RA - DHCPv6 Server - Dynamic DNS -

Just to be clear. It's no router when you run it as a bridge.
Yes, it's transparent. You don't have to setup anything on the Access Point. The only thing you might want to do is to configure an IPv6 address for the AP so you can access it through its IPv6 address. There are several different methods like static configuration, stateful or stateless.

Yeah that is bad idea!! Most soho wifi routers dhcp server is very limited, many of them will not even allow you point to a different gateway other than its own IP. I would suggest TURN it off - you have zero use for it since pfsense would be your dhcp server.

ok, it's working!. I have sucessfully connected a HE tunnel and it's working, as I can ping from the pfSense box to ipv6 sites and it works (with horrible lantency, but it works).
But it seems I have not been able to make DHCP work as it should, because the DHCPv6 leases does not appear except for and iPad I have on my network, but when checking on the iPad it only seems to receive the ipv6 dns servers and no ipv6 address, and the test-ipv6.com check does not show any ipv6 address…
I can post the screenshots of my configuration if anyone can help me.

First, you need RADVD enabled and working (In Unmanged or Assisted mode). Leave DHCPv6 alone for now, it's badly broken on Windows, not implemented on Android, and used in whacky ways on Bitten Fruit Co. products.

the services status shows radvd working, but I'm not sure if its well configured… I have tried in Managed and Assited mode and seems to make no difference.

Automagical options for you for RA are: "Unmanaged" (SLAAC method)
Even with RA="Router Only", you can always manually give a host on a LAN an IPv6subnet/64-number yourself.
Config your LAN static as you like.
The /48-part is HE, the next Word-part is your-subnet, then the last 64-bits are up to you, like say ::abe 8) -

I have more that 20 devices/computers, I would like to leave that work to the DHCPv6 server. -
I have started a new thread because of my DHCP problems on https://forum.pfsense.org/index.php?topic=126054.0 because I think the subject has changed from the original one. Please follow it there.
Thanks.
