![]() ![]() Set the X-Forwarded Header Mode to off.The settings here are optional but will limit the amount of information displayed in the Squid headers. Headers Handling, Language and Other Customizations This will be useful once we’ve installed SquidGuard. This enables the SquidGuard logs to be viewed from the Real Time tab alongside the Squid Proxy logs. Check the Log Pages Denied by SquidGuard box.This will log your Squid traffic so you can see how Squid is behaving if you need to troubleshoot anything. We’re going to leave this feature disabled as well. I don’t recommend Man In the Middle SSL filtering except for specific purposes by people who understand what they’re doing. This enables you to filter SSL connections but also breaks the HTTPS validation that is meant to happen in your browser. Squid can replace the proper SSL certificate from the website you’re trying to access with its own, decrypt the connection, and re-encrypt it with its certificate. But to do this, you essentially need to break HTTPS. So we’re not going to enable the Transparent mode in this guide, but you can help both modes without issue.Īs I mentioned above, it’s possible to transparently proxy HTTPS connections. And in this mode, all TCP internet traffic is proxied (HTTP and HTTPS). The explicit mode requires you to configure each client to “request” access to the proxy. Since most internet traffic uses HTTPS, the transparent mode has limited scope for ad-blocking but can still be useful for caching. However, this mode will only proxy HTTP traffic over port 80, not HTTPS traffic (unless you configure Man In the Middle SSL filtering – more on that below). In transparent mode, no configuration is required on your clients (computer, tablet, smartphone, etc.) – their traffic will be transparently proxied. Proxy servers can work in one of two ways: transparent or explicit. Set the Outgoing Network Interface to Default (auto).If you add additional interfaces to your pfSense box and want the traffic from those interfaces to go through Squid, you’ll need to select them here. Make sure LAN is selected in Proxy Interface(s).If your pfSense box is using both IPv4 and IPv6, select IPv4+IPv6 from the Listen IP Version drop-down menu.We will first configure our proxy server before we enable it. Leave Check to enable the Squid proxy box unchecked for now.If you want to tweak your local cache settings later, you can do that from the Squid Settings Local Cache tab. If you try to configure the proxy without accepting the default local cache settings, you’ll be prompted to do so and lose the settings you configured so far. Any settings that are not mentioned should be left at their default values.īefore configuring Squid, we first need to go to the Local Cache tab and accept the default local caching settings by clicking Save at the bottom of the page. Only the ones we need to achieve our goal. ![]() Our purpose is to set up ad-blocking with Squid, so we’re not going to go into every sub-menu. We’re going to go over configuring Squid section by section. You’re taken to the General tab of the Squid Settings. From the top menus, select Services > Squid Proxy Server. Now that Squid is installed, we’ll configure our new proxy server.ġ. This guide assumes that you’ve got a working pfSense system configured with working WAN and LAN interfaces and that you’ve got GUI access. WWe’regoing to show you how to configure Squid and SquidGuard (SquidGuard is an extra component of Squid that enables list-based filtering) on pfSense to block ads on all of your devices. And that’s what we’re going to be using Squid in this article. There are some excellent reasons to want to get rid of them. They violate your privacy, consume your bandwidth, and are a major vector for malware. Organizations that block access to Facebook, for example, are performing content filtering.Īnother use for content filtering is to block ads. Content filtering means blocking connections to certain domains or IP addresses. This speeds up your internet browsing because fetching content from the proxy’s local cache is much faster than re-initiating a download over the internet.Īnother purpose is content filtering. This means that the proxy server will save some content locally so that the next time a client requests that content, it will be served from the cache rather than going out to the internet to download it again. Why send your traffic through the proxy server? There are a few reasons. Your traffic leaves your device, connects to the proxy server, and then goes off to its ultimate destination from the proxy server. A proxy server is an intermediary server that sits between your device (laptop, tablet, smartphone) and your ultimate internet destination (). ![]()
