how do i set pfsense to get ipv6 from isp

firefox

@stephenw10
Is there a way around this?
Any page loaded in a second or two
Loads after 10 or 20 seconds

You can probably configure the clients to use only IPv4 or use v4 by default.

Otherwise you need to either have fully functioning IPv6 or none.

While you can normally adjust a OS preference to ipv4 from v6. Some devices are more difficult than others, and can be difficult to actually disable completely.

If you are having issues with ipv6 - the simple solution is just not provide it at all.. Which is easy enough to disable at pfsense. Its much easier to do that way, then trying to configure each client to not use ipv6 or prefer v4 over, etc.

I don't provide any automatic IPv6 to any clients on any of my vlans. But I can configure clients on the vlans I have it enabled manually to use it..

Smart move! Here you can see why:

I wouldn't put much stock in what that guy says. He doesn't understand IPv6 enough to make those claims. In fact some of what he said is nonsense.

I made some comments on on that video last month.

@ firefox

As for IPv6, that is where the world is moving, so disabling IPv6 is not the fix. All you're doing is hiding the problem. If your ISP has a problem and they can't/won't fix it, there's always he.net.

stephenw10

Yes, a fully functional IPv6 connection is the way forward here.

haha - "some" its pretty much all nonsense, I wasn't going to sit through 30 minutes of nonsense.. so just skipped through it.. Every part I stopped on was just nonsense.

Some of his comments as well - don't read books, don't read rfc's - watch videos? Come on!

I would agree disable ipv6 is not a "fix" What it is, is a way for you to get up to speed with your understanding before you use what yes is the future.

Until such time that you have a NEED there is no reason to have it enabled unless you actually understand how it works, how to secure it and how it functions to be able to troubleshoot it when things go wrong.

Many users have it and don't even know, they might not be having any problems, they might not attribute issues they are having with IPv6, etc.

Do you have a web server running if you don't need one, do you have ftp running when you don't need one.

Security 101 says if your not using something - then it shouldn't be enabled. If you have no use for ipv6 then there is little reason for you to have it up and running. Unless your actively going to be using it, or experimenting with it.

I would not say you should disable your IPv6 unless you're having issues. But if you are, there is nothing wrong with just turning it off until such time that you actually need it. Or are willing to spend the time needed to get up to speed and properly configure your network for its use.

You can for sure bring up ipv6 in limited fashion to use and play without until such time your are comfortable and know enough to properly deploy it across your full network.

What is nice about pfsense - it gives you the ability to do just that. Vs some soho router where it on or off, with limited ability to manage it or monitor it, etc.

The mentioned hurricane electric is a very controlled way to bring ipv6 into your network. Limit its scope or not. With no need to have to deal with your isp lack of ipv6 support or inadequate type of deployment.

That pretty much sums up his videos. I have tried to watch a couple of others but couldn't stomach them. I guess he's one of these "experts" who's read a couple of magazine articles and now knows all there is to know.

It reminds me of a job I was on a few years ago, where the woman, who was the office manager, got annoyed because I plugged my computer into the switch with a CAT 5 patch cord. She was convinced it was going to affect her network, which we'd just cabled with CAT 6. She knew that because her husband (he's a veterinarian) had read some magazine articles.

Thank you all
Although I would like it to work properly
I currently do not really need ipv6
I wanted it to work to test something
And it's probably not easy
One of the times I tried I was left without an internet connection
So i had to restart pfsense and select restore to previous state
Because no matter what I did it was left without an internet connection

If it was as simple as changing the settings and clicking apply
I would do that
But as I wrote down
I was left without internet
And even if I changed the settings to the previous mode it did not work

Only when I started pfsense and selected restore to previous state
It's back to work

@James, you and Lawrence from Lawrence System have been working with IPv6 for many years. Even now he don't use IPv6.
About the video, well nonsense is really a strong word. I think the point he wants to make, that average users don't know how to modify IPv6. By default most devices use IPv6 are not configured correctly.

JKnott

@akegec

Actually, considering what he was saying, nonsense is not too strong. He was flat out wrong. See my comments on that video As for Lawrence, I don't know what he does with IPv6. My interest in his videos has been mainly with Unifi APs and I don't recall him ever mentioning IPv6. However, he may be doing a video on a data tap, as per my suggestion.

As for IPv6 in general, I find some people just dismiss it, because they don't want to learn and think it's OK that the Internet will be crippled as long as IPv4 is the main protocol. I saw the address problem with IPv4, shortly after I started learning about TCP/IP in the mid '90s. Not long after, I read about IPv6 in the April 1995 issue of Byte magazine and realized that was the way to go.

firefox

@jknott

bad luck
Now for some reason it has returned to the state where each page loads after 20 seconds or 30 seconds even though ipv6 is disabled (in pfsense and pc)

How to fix it
So that it will work without any problems

JKnott

@firefox

Well, it's obviously not IPv6 causing this. What happens if you connect a computer directly to your modem?

firefox

@jknott
In direct connection to the modem {this time as a router) works fine
I tried to change the settings in pfsense
And again I was left without an internet connection
And I had to do a restore to last settings

Is there a log that lists all of these changes and what is wrong?

stephenw10

Config changes can be seen in Diag > Backup/Restore > Config History.

Actual errors will be in the System log.

But if it's just misconfigured you'll have to troubleshoot it.

Steve

firefox

@stephenw10
I know where the Backup/Restore
It does not respond
The only way it responds if I ssh to pfsense
And selects there the option of restore
Which is actually the same thing but there it responds

If I change a setting to something specific and it does not work
So I return it to the same thing that was before
It should work without doing a restore

What's happening now
When I change the settings of ipv6
And it does not fit (the Internet is disconnected)
I change back to the same settings as before
The settings change but the link to the Internet remains disconnected
The internet link only comes back if I do a restore
