Unofficial E2guardian package for pfSense
-
While doing pkg add -f https://e-sac.websiteseguro.com/e2g/e2guardian-5.0.2_7.txz, it failed to install.
It says, pkg: Missing dependency 'openssl'
How do we resolve this error ?
Follow instructions on the first post.
Add the repo and then install from guiDo we need to configure WPAD, DNS and DHCP Options ?
PS: Do you have any tutorial on how to configure E2Guardian for http and https filtering like the ones in youtube for squid and squidguard for reference ? Thanks

Do we need to configure WPAD, DNS and DHCP Options ?
Only if you want or have a lot of sites on non standard web ports lie 8080,8081, etc..
The transparent proxy on e2guardian works really nice.
PS: Do you have any tutorial on how to configure E2Guardian for http and https filtering like the ones in youtube for squid and squidguard for reference ? Thanks
I have this video on youtube with basic setup instructions. The audio is in portuguese but following the images and a youtube translated cc, I guess you can configure it.

I don't see any firewall rules setup on the video ? Is there a need to create firewall rule to redirect traffic to 8080 and 8081 ?

The package creates automatically for transparent proxy options.
Select the same options I set on the video and take a look on realtime tab.

ok thanks Marcelloc

Marcelloc, what auth plugins ip address ?
Why are some options have (on) and some are (off) ?
What does on and off means there ?Also I checked on console e2guardian -version, it only show '–enable-sslmitm' and not '--enable-sslmitm=yes', does that mean e2guardian installation does not support SSL traffic interception ?

Marcelloc, what auth plugins ip address ?
Check groups based on clients IP address.
Why are some options have (on) and some are (off) ?
What does on and off means there ?on and off are the default config options. Check all (on) options to use setup defaults. Most are selected automatically on package install. Any option you select, will be enabled on config files.
Also I checked on console e2guardian -version, it only show '–enable-sslmitm' and not '--enable-sslmitm=yes', does that mean e2guardian installation does not support SSL traffic interception ?
It has traffic interception compiled. Select the CA under daemon tab to enable check certificate sites (splice all feature on squid) and Filter SSL under group options to intercept the connection with MTIM(requires the CA installed on clients browser to work correctly)
-
Marcelloc, is it fine to create the INTERNAL CA using pfsense system/certificate manager/CAs OR should it be done thru console as you have said here https://github.com/e2guardian/e2guardian/wiki/MITM–-Filtering-HTTPS, Generating the necessary SSL certs.
-
Create from GUI (system/certificate manager/CAs). On pfSense, there is no need to create certificates under console.
-
Thanks for confirming.
Another thing is:
1. If I download the shallalist, how will I know that it is done downloaded aside from the message prompt ?
2. In the Group Menu, the is this Pics (option) under Access List , where is that Pics in the ACL ?
PS: Even if I uncheck / disable the E2Guardian in the daemon page, it still shows STARTED / RUNNING on the status/services.

Marcelloc,
I have followed your youtube example, I create the CA on pfsense gui, I selected filter ssl sites forging ssl certificate, save, and applied,
but when I visit https sites, I get the following error on my chrome browser. I am using 2.4.3 pfsense version.I even tried install the CA cert on my browser but still the same error.

UPDATE 5.14.2018 3:45pm :
Since I am getting this error above, I tried to shutdown my chrome browser. And I tried again surfing https sites, and it is ok now.
So Marcelloc, does this mean, I need to install the CA certificate on client browsers ? -
Option 1 Select the CA under daemon tab to enable check certificate sites (splice all feature on squid). No certificate is required on client.
Option 2 select option1 and Filter SSL under group options to intercept the connection with MTIM(requires the CA installed on clients browser to work correctly)

Yes I have selected the CA under daemon tab. What is option1? I have also selected Filter SSL under group options. I have followed all in your youtube video sample.
However, I have resolved it by installing the CA certificate on client browsers. But I need it to be that I don't need to install the CA cert on the client browsers.

You can configure ssl with or without interception. Follow option 1 to only check certificate but do not intercept
Follow option 2 to check certificate and intercept connection.If you do not want to install certificate on client, do not enalbe filter ssl on group options.

Like I said, I have done option 2, which is selecting the filter SSL in group options. That is why I wonder what is lacking in what I have followed. I have checked the configurations more than 10 times already.

marcelloc, is there a possibility that on your youtube, you have installed CA in your browser?
-
Sarg package is alive again on unofficial repo to create e2guardian reports.
As I updated repository structure recently, update the repository file before package installation.
fetch -q -o /usr/local/etc/pkg/repos/Unofficial.conf https://raw.githubusercontent.com/marcelloc/Unofficial-pfSense-packages/master/Unofficial.conf -
Marcelloc,
I have reinstall pfsense again awhile ago and followed your youtube again up to the point where you deselected Filter SSL in group options. In your example, when you browsed facebook, it should err_ssl_protocol_error but on my case, it still opened facebook site even I restart my Chrome browser.
UPDATE1: I have fixed this err_ssl_protocol_error by setting my ip address configuration of my computer to automatic. However, my new problem is back to

NET::ERR_CERT_AUTHORITY_INVALID
This means you are on the same point as 3 posts before.
Do not select Filter ssl sites forging SSL certificates if you do not have firewall CA installed on your client's browser.

Sure I can deselect Filter SSL Sites forging SSL Certificates but doing so will get me err_ssl_protocol_error.

Try running Windows Network Diagnostics.
ERR_SSL_PROTOCOL_ERRORUPDATE 1:
So I read that Splice All:
This configuration is suitable if you want to use the SquidGuard package for web filtering.
All destinations will be spliced. SquidGuard can do its job of denying or allowing destinations according its rules, as it does with HTTP.
You do not need to install the CA certificate configured below on clients.And it is mentioned that E2Guardian SSL interception is "Option 1 Select the CA under daemon tab to enable check certificate sites (splice all feature on squid). No certificate is required on client."
And also in the youtube video, before you selected the Filter SSL Sites forging SSL Certificates, you also got err_ssl_protocol_error while surfing to facebook and youtube.com
I can only think of two things:
1. You need to install the CA on client browser and select Filter SSL Sites forging SSL Certificates OR
2. There is something broken with E2Guardian as it does not do MITM (SSL Interception)My goal here is to do http and https mitm ssl interception without having to install CA on client browsers.
