Guide to filtering web content (http and https) with pfsense 2.3
-
I also have this wireshark done where I can see that it made a CONNECT method to facebook, then it has established connection, send client hello but later have RST and there is no SERVER HELLO thus no application data received.
What could I miss here.

lets try without the wpad and use just the transparent, set proxy direct does it work then?
If you still cannot access https sites then post you squid config. -

If you still cannot access https sites then post you squid config.If I use only the http proxy without the ssl mitm and set browser to auto, then the http proxy filter works.
If you are saying to setup http transparent proxy and ssl mitm filtering and install cert to client device and set browser proxy, then I have not done this yet.
-
and install cert to client device and set browser proxy, then I have not done this yet.
Just use splice all for mitm (and use the cert created in pfsense under SSL Man In the Middle Filtering\CA).
Set browser to direct.
This will use transparent proxy for both http and https.If this works then there is an issue with your WPAD.
If this does not work then something is broken. -

If this does not work then something is broken.What do you mean for "Set browser to direct", is this the automatic detect settings ?
On the other hand, my wpad only have the following inside:
function FindProxyForURL(url,host)
{
return "PROXY 192.168.1.1:3128";
}I am not sure what you example below means so I use the example from pfsense wiki.
function FindProxyForURL(url, host)
{
if (isPlainHostName(host) ||
shExpMatch(host, "*.local") ||
isInNet(dnsResolve(host), "192.168.1.0", "255.255.255.0"))
return "DIRECT";return "PROXY 192.168.1.1:3128";
} -
yeah turn off automatic detect setting so the traffic goes direct and gets intercepted by the transparent proxy.

By turn off, you mean uncheck the automatic detect settings and others options as well ?
-
yes

May I ask though, what is the exact version of pfsense that you are using just for comparison. If this will not work, then I will need to reinstall my pfsense box, maybe its broken.
I am using:
2.3.4-RELEASE (amd64)
built on Wed May 03 15:13:29 CDT 2017
FreeBSD 10.3-RELEASE-p19On the other hand, below is the screen shot of my testing NOT USING WPAD but setup the browser proxy.
Also, I tried direct approach that you said, and the result the same error as before.
What exact pfsense version are you using ?
-
2.3.4-RELEASE (amd64)
Something is broken. -
2.3.4-RELEASE (amd64)
Something is broken.what is in your wpad file?
did you install your pfsense or upgraded to 2.3.4 release?
-
wpad is in the guide.
I have been upgrading since i joined.

Hi,
I am new to pfsense, can someone have a look at the attached image and tell me if it looks correct please.
![pfsense Nat PortForward 1.png](/public/imported_attachments/1/pfsense Nat PortForward 1.png)
![pfsense Nat PortForward 1.png_thumb](/public/imported_attachments/1/pfsense Nat PortForward 1.png_thumb) -
I have followed this guide.
When I run proxy test it shows that I am under proxy. Google works fine, and so do most websites. But such websites as Amazon won't load, gives error.
Any advice would be greatly appreciated.
-
Post your squid config. Are you using just WPAD or Transparent proxy with mitm (cert of all devices) or Transparent proxy mitm set to splice all?
The best setup i found to use is WPAD and transparent proxy with mitm splice all, set devices to auto config.

Hi thanks for your reply.

if you set squidguard to allow all do still get the issue?

Hi, thank you for the reply.
I have it sorted now, i didn't go to internet properties/connections/LAN settings - tick automatically detect settings
At the moment I have Wpad.dat working, I also have MSSL MITM working on splice all, I have android working now (manually entered wpad.dat address).
Is this method the best functioning method, or am i better to setup a websever to to host the wpdad files? What are the main benifits of setting up a VM hosting these files?

Not sure, maybe if you had a very large number of users you could use another webserver for the wpad.

Even if you left that unticked the transparent proxy should have still connected you, verify that the transparent proxy is working (e.g block port 80 and 443 and use a program that gets updates form the net to check).

Hi,
I am new to pfsense, can someone have a look at the attached image and tell me if it looks correct please.
Was looking at this guide, https://doc.pfsense.org/index.php/Redirecting_all_DNS_Requests_to_pfSense and comparing to your screenshot. What are the implications of unchecking the "invert match" box and not disabling NAT reflection?
