IPV6 Static IPV6 address
-
true - my point is I think it would be easier to just use a specific /64 as transit and give the users a /128 to set..
But yeah the isp could do it a bunch of different ways - which is why he needs to get with his isp for the specific instructions allowing him to use the /56 behind his router.

In where do you see I am using /56 on an interface? There are /64 on interfaces in the example.
Your need to get with your ISP on how to set it up..
My ISP does not provide PFSense support.
So my setup can be (we assume that I will have /56 network)
WAN:
IP: 2a00:900:10:0001::2 / 64
Upstream GW: WAN 2a00:900:10:0001::1LAN:
IP: 2a00:900:10:0101::2 / 64
(there is no Prefix ID when LAN IPV6 configuration type is set to "Static IPv6")Should this work without setting DHCP6 on LAN side?

Has ZERO do with what your using.. It has to do with how your suppose to set it up.. What is your transit, do you set static - then what are the details. Are you suppose to use slacc, are you suppose to use dhcpv6-pd, etc. etc.

An ISP providing pfSense support would be the same as an ISP providing Cisco or D-Link support. The equipment is irrelevant. It's the protocols that matter.
-
I am only asking what is best practice from PFSense perspective using example IPs. I am not asking ISP how to set up PFSense, I am asking it here. I am not asking ISP information from you, that is provided by ISP.
Lets put it this way.
As an example ISP provides a customer following network:
Network: 2a00:900:10:1000:: / 56
GW: 2a00:900:10:1000::1 / 64What is suggested setup using static IP on WAN side?
Edit: Try&Error method started...
Edit2: I hope someone writes a tutorial how to setup static IP based configuration as good as they are WAN DHCP client ones... -
This post is deleted! -
Lets split this in easy questions. ISP provides /48 network a : b:c::
On WAN interface, static IP is being used. IP is a: b:c::1
What is length? /64 or /48?
-
it would NEVER be /48... You would never set a mask/prefix on a interface to anything other than /64 or /128.
If your isp is giving you a /48 it needs to be routed.. It would never be on any interface, if they are directly attaching you to a /48 they are doing it WRONG!!
-
Ok. This is clear. So my setup is building up. Lets continue.
ISP network a: b:c:: /48
ISP GW a: b:c::1 /64
My WAN IP is now a: b:c::2 / 64Then LAN side. I have subnets behind PFSense, but also individual devices.
Lets use the next /64 for LAN.
Static LAN IP: a: b:c:1::1 / 64This must be correct, right?
-
Yes you can use any of the /64s out of the routed /48 on your lan.. But the 1st one might not be your transit.. They might give you something other than part of your /48 as your transit.
Or maybe they just use link-local.. Maybe they want you to use a /128 on your wan, maybe they want you to just let your wan get via slaac.. Have no idea - which is why get with them!
-
johnpoz, please forget ISP already. I am building up IPV6 reference setup of configuring PFSense for myself as a learning curve. I asked for best practices. And best practices for PFSense only. Something I can use later with ISP connection. It was clear after two posts that the network they provided will not work. I will get a new next week.
But thank you for the confirmation and the clarification of transit detail.So, lets move on into practice. There are quite many parameters needed to be correct in order everything to work.. I can assume. I tried following in PFSense.
Network setup:
PFSense LAN IPV6: 2001:1111:2222:3333::1 /64DHCPv6 server enabled using following parameters:
Range start: 2001:1111:2222:3333::100
Range end: 2001:1111:2222:3333::1ff
Prefix Delegation Range start: 2001:1111:2222:3334::
Prefix Delegation Range end: 2001:1111:2222:333f::
Prefix delegation size: 64
Router mode: ManagedSo my HW setup is:
PFSense [LAN] <--> [WAN] SubRouter1 [LAN] <--> PC [NIC]PFSense LAN IP: 2001:1111:2222:3333::1/64 -> OK (set manually)
SubRouter1 WAN IP: 2001:1111:2222:3333::1c7/128 (DHCP seems to work OK)
PC IP: 2001:1111:2222:333e:6d12:8c45:1b7a:6388/128 (DHCP subnet provisioning seems to work since PC gets an address from 333e subnet OK)Lets ping:
PC to SubRouter WAN: YES
PC to PFSense LAN: YES
Subrouter to PFSense LAN: YES
SubRouter to PC: YES
PFSense to SubRouter WAN: YES
PFSense to PC: YESSo this setup seems to work on IPV6 level. I don't know if that is best practice or even suggested setup, but maybe someone can comment on that (rather than asking me to contact ISP)... and sorry, I am not ungrateful or anything. Maybe there is language barrier and I can't express myself clear enough.
What surprises me a little bit is that I haven't configured anything like "Default gateway" in SubRouter nor PC. I can see that PC has default IPV6 gateway to SubRouter's fe80-address. So it works that way just fine. Because PFSense LAN IP is in the same subnet as SubRouter's WAN routing works between PC and PFSense. But I wonder what happens when I ping Internet from PC. That remains to be seen after I have working ISP IPV6 connection next week... (I would be surprised if Subrouter knows how to handle Internet traffic, but maybe IPV6/PFSense is smart enough for that too automatically...)
Ax.

And yes, I wrote a little bit length message but I hope my learning notes helps someone else. I found quite many posts of how to set IPV6 on PFSense, but almost none related to Static IPs or using DHCP the way I need to. Also old seniors like me whom have done everything with IPV4 past 30 years there are quite many details done differently.
-

I asked for best practices.
How is that possible, when you don't know what the ISP is providing? The setup for DHCPv6-PD is quite different from assigned static addresses.

I'd suspect most people get IPv6 from an ISP that uses DHCPv6-PD. Again, until we know what you're dealing with, it's hard to offer advise.
-
Please forget my ISP already.
I was building a reference setup using an initial requirement that IPV6 address from ISP is static.For those whom are able to comment my setup I would be appreciated. Thank you.
-
@JKnott I'd suspect most people get IPv6 from an ISP that uses DHCPv6-PD. Again, until we know what you're dealing with, it's hard to offer advise.
Yes I can imagine that too. After reading instructions and comments.
But one more time: I am dealing with the setup I have specified and trying to build up a reference setup using those prerequisites. Got it?
-
Well then sure if you want to use the first /64 out of /48 as your transit - then sure that is possible.
-
In this reference setup the first /64 is assumed to be a transit.
But what I would like to know if is this a correct way to publish subnets to subroutes (copied from a message above)?:
Prefix Delegation Range start: 2001:1111:2222:3334::
Prefix Delegation Range end: 2001:1111:2222:333f::
Prefix delegation size: 64Ax.
-
So your going to do downstream prefix delegation? The range is only use to use part of a larger prefix in your actual delegation. Say you want to delegate the 2nd half of larger prefix, or maybe you want to only delegate the middle of the prefix to downstream devices asking for delegation - ie downstream routers.
-
Let me clarify the idea.
Lets assume ISP gives /56 network. In this theoretical example it is then 2001:1111:2222:3300::
So, 2001:1111:2222:3333 was the LAN network of PFSense. I think it was stated that SubRouters need to have /64 subnets within that /56 network? Otherwise they are not able to route to ISPSo I assigned 3334:: to 333f to be delegated to subrouters using /64 delegation size. Which they got and pinging works inside of the internal network built by this example (between 3333 and 333e and over the SubRouter).
