I have a Ubiquiti Ethenret and WiFi network and their software will give me the discovery capabilities, and my custom OpenBSD router gives me the traffic inspection features (using Darkstat). Source: over 2 years ago

A friend of mine is a tech wizard, and he hooked me up with a home built router that uses pfSense, which comes with a program that does what you're asking for - darkstat. Source: about 3 years ago

I do have darkstat monitoring traffic on my egress interface. I also block access to UDP port 53 from untrusted hosts (I will change it to silently redirect to my official unbound DNS servers later). Source: about 3 years ago

For more information about vnStat use "man vnstat" or visit: Http://humdi.net/vnstat/. Source: about 1 year ago

Something similar to vnstat (which monitor the bandwidth usage): https://humdi.net/vnstat/. This tool doesn't necessarily take into account only the ports 80 and 443, it can be generalized to all the traffic flow, but that would be a great if it does. Source: about 1 year ago

Take a look at https://humdi.net/vnstat/ - it should work on *BSD and I think there's a package for pfSense (and by extension should be there for OPNSense as well). Otherwise it's not too hard to setup to run at start up as well. Source: over 2 years ago

If you don't want to run a stack can try something simple and lightweight like vnstat (https://humdi.net/vnstat/). Source: about 3 years ago
