Despite months of config, still having connection issues

rheritier

I'll start with transparent mode.
On the ACL, should putting what I have below helps limiting the system blocking some websites? (example: *.com to leave all website in .com accessible)?
I need to learn more about the DNS and its configuration also.

@rheritier I just have that set as .* for allow all. Squidguard does my blocking

Keep it simple

Regular expression based works great

rheritier

Thanks @JonathanLee, I like that!!
Will try it now

So I did everything so far and it seem it is a bit smoother and block less things.
But I still have for example difficult access to Amazon App. I have to deselect the wifi, let it charge a bit, reselect the Wifi and then it'll work propertly.

Here is the screenshot of my Firewall block. Anyone sees something specific??

@rheritier do you have any IPv6 access?

rheritier

@JonathanLee Hi Jonathan,
I'm not sure what to think and tell you since both test seems to show different results.
Is there another way to test?

@rheritier does your wan configuration on PfSense show anything for IPv6?

rheritier

@JonathanLee here is my WAN config:

The tests are different.

You visited https://test-ipv6.com/ from your PC.
You should have run the ping version IPv6 test also from your PC, like

C:\Users\Gauche>ping -6 2001:4860:4860::8888

Envoi d’une requête 'Ping'  2001:4860:4860::8888 avec 32 octets de données :
Réponse de 2001:4860:4860::8888 : temps=17 ms
Réponse de 2001:4860:4860::8888 : temps=17 ms
Réponse de 2001:4860:4860::8888 : temps=17 ms
Réponse de 2001:4860:4860::8888 : temps=17 ms

And and before running such test, why not asking your PC if it has any IPv6 connection available ? :

C:\Users\Gauche>ipconfig /all

Your pfSense IPv6 ping test (Diagnostics > Ping) shows that pfSEnse has an IPv6 connection.
Your WAN setup says it used the DHCPv6 client to obtain "IPv6".

Most probably, you should set up your LAN interface to use IPv6, like this (example ) :

and the DHCPv6 LAN server :

also :

This WAN IPv6 :

is also listed here : Status > Interfaces under the WAN interface.

Hi @Gertjan ! Thanks!
So I did the following:
Ipconfig /all (on Mac, it seems to be /sbins/ifconfig) and here is the result (I hided some info):

I tried to ping as said at the beginning but it didn't give much (I search and found on Mac it should be ping -l...but it didn't work either):
ping -l 2001:4860:4860::8888
ping: invalid preload value: `2001:4860:4860::8888'

Then I followed your recommendation and had the same setup for the 1st screen (set up LAN interface to sue IPv6), change the range as per your example from 2 to 86 (mine was from 1000 to 2000), and on last screen, changed the Router Mode from "Assisted" to "Managed".

I saw you hided some info so did the same. Here is what I have in Status/Interface/WAN (by the way, what is this big "Release WAN" in red? should I do it?)

Not really.
See ipconfig command for Mac and ... you'll get no answer.

I wanted to see this :

This doesn't hardware aspect of the interface, but : It got an IPv4 using DHCP, who is the DHCP server (192.168.1.1 == pfSense), and the same info about IPv6.
Also : who is my DNS for this PC (pfSense).

@rheritier said in Despite months of config, still having connection issues:

ping -l 2001:4860:4860::8888

'-l' ? Try

ping6 2001:4860:4860::8888

Although a ping using ICMPv6 will only work if you obtained IPv6 by using DHCPv6 (client) or a static IPv6 assignment (don't forget the IPv6 gateway, don't forget the DNSv6)

@rheritier said in Despite months of config, still having connection issues:

by the way, what is this big "Release WAN" in red? should I do it?

On your WAN interface, you use DHCPv4 and/or DHCPv6 to obtain a IPv4 lease and / or IPv6 info.
Leases can be released

So that's what the button does. You rarely, if never, need to do that.
If you were editing the DHCP server settings of the upstream server, you would : validate your settings, and the release, and renew the IPs of your WAN to have tour pfSense reconnect again using the new lease info.
You could also remove the WAN cable for a short moment, and re insert it.

Btw : my pfSense LAN :

On the DHCPv6 LAN server page : check :

JonathanLee

Also if you enabled DHCP6 you need to set Squid to listen on IPV6 too as clients have IPv6 access

rheritier

@JonathanLee noted!
This is the only change to bring to do so, right?

JonathanLee

@rheritier yes as long as IPv6 clients know where the proxy is your good to go.
