If you’ve ever wanted to access your VSOL ONU’s web interface (usually at 192.168.1.1) from your LAN (say 192.168.0.0/24), you might have hit a wall—especially if your router doesn’t allow assigning multiple WAN IPs. In this guide, I’ll walk you through how to bridge that gap using a Raspberry Pi or any other device with at least two network interfaces. We’ll use the following setup Prepare the Raspberry Pi Connect the Pi’s eth0 to your Router’s LAN port. Connect eth1 (USB-to-Ethernet adapter or secondary port) to ONU’s bridge port. Your Pi now has two interfaces: one in your LAN and one going to the ONU. ...

In the modern world with encryption all around I was fascinated by how some ISPs are able to censor content on the web. Whether or not censoring is good or bad could be a debate for another day. Today, I will share the technical details around censorship and a technique used by ISPs called Deep packet Inspection (DPI). It all started when I could not reach raw.githubusercontent.com using my ISP. Being an engineer I was curious to understand how they are able to censor content and how to potentially bypass it (because raw.githubsercontent.com usually hosts GitHub scripts which I was using for home lab automation). ...
