OPNsense Web Filtering/Proxy Configuration - Virtual Lab Building Series: Ep4

Could be done easier with blocklists in Unbound or the sunnyvalley plugin (Zenarmor, a.k.a Sensei)
No need to install a client cert, no risk of mitm attacks.
As a bonus you get to block ads as well :) Blocking ads will save more bandwidth than Squid and protect you from malvertising.

Nice video!

Is that possible to do blocking for certain users/IPs? I am still newbie on configuring firewall and the Zenarmor Plugin needs to be paid in order to do so..

What are the details of the anti lockout rule?

opnsense can you do port triggering; along with malware blocking?

thank you very much for the contribution

Thank you very much for your videos! For some reason, I do not see the "Web Proxy" option under "Services" do you perhaps know why? Thank you!

After 2024 squid is a plugin, but it never starts after install and configuration. Any pointers?

Great vid - thanks! Any idea how to solve this error when starting the service "ERROR: ACL not found: Safe_ports" ?

The rules seem to block everything from my network.. When restarting squid proxy service, returns: "Segmentation fault
Performing sanity check on squid configuration."

Hello sir, I really appreciate your work and I am learning a lot form your videos but the issue is, things have updated. Web Proxy have become os-squid plugin -> which we have to configure. And it took me quite a while to figure it out. But after setting up everything, there is a segmentation error with the plugin, which has no solution so far as I read their github commits and texts. I would request you to update this part with some alternative . Thank you

Thanks alot! everything working as you did! Thanks

Hi
