In this guide “HOW TO SETUP HTTP/HTTPS WEB PROXY FILTER ON OPNSENSE”, we will go a step further by trying to use the squid proxy feature that comes with most open source firewall solutions to block and prevent unwanted traffic from flowing into our network or from being accessed by our users.Read More
So far, we have used the pfsense router cum firewall and the packages that it provides to serve as a firewall and proxy for our corporate environment. We tasted the powers of SquidGuard, were we where able to filter contents, only allowing access to certain sites using the common ACL rule, while blocking access to every other thing.
In this guide, “PFSense Squid Active Directory Authentication”, we will go a step further to grant access to the internet and allowed sites only to those who need access while completely denying access to all those who do not need it using microsoft active directory authentication.

WPAD stands for web proxy auto discovery protocol. It is a protocol that helps clients to locate the URL of a configuration file using DHCP and/or DNS discovery methods. In our guides so far, we have installed pfsense firewall and made some basic configurations.
We also went as far as installing squid and squidguard, to help us cache, monitor bandwidth usage and allow or block access to certain sites.
Web proxy is a topic that has been discussed thoroughly on topnetworkguide.com website. This is because most of the threats that you will come across during your career, will come through internet activities, most from your clients who innocently surf and download contents from the web.

IPFire uses squid proxy to control access or to log and cache visits to web pages, optimization of bandwidth and speed. It features a proxy cache as well as an update accelerator to help in distributing windows and linux updates and patches centrally to all client computers in the network.
IPFire also ships as an addon, the squidClamAV that takes care of data privacy.
All these and more, we will be covering in this “Complete Squid Proxy Configuration Guide on IPFire Firewall” series.
So far, we have considered the benefits of having a properly setup and monitored proxy in our network. We installed the somewhat inbuilt squid monitoring tool called cache manager, we even manually went through the access log files, and then we installed and configured calamaris to further monitor our squid proxy server.
