The final touches
It has been a long time since the last devlog, but I finally added some quality-of-life features.
The admin page
PiRouter serves an admin webpage on a standard ip 192.168.50.1 behind the auth (default password is Admin, but don’t tell anyone). It has a number of configurations for the wifi and proxy. It also has a theme switch, but i don’t think that anyone will ever use the light theme ;p
Other stuff
Fixed some bugs and added a bit more configurability during the installation process.
That’s it!
I think that this will be my last devlog, so thanks to anyone watching this. Bye!

Virtual AP update
From now on, you don’t need an additional USB dongle for Pi Proxy Bridge to work!
Better interface
Updated the installer. It now starts by asking which mode you want (virtual interface or second adapter). Then, it asks configuration questions like
- Hotspot SSID
- Hotspot password
- Hotspot’s channel
- Whether to use 5GHz
README update
I also updated the README to better explain how my project works, as well as some setup tips.
Ship #1

Say hi to my project!!
Pi Proxy Bridge is a setup where a Raspberry Pi works as a WiFi-to-WiFi proxy access point with support for Xray Core.
At home, we have a security webcam that doesn't work without a proxy, but it can't connect to one itself. So, I decided to build my own proxy bridge for it.
This is the first working version, and I want to expand this project further, probably wrapping everything up in Docker and adding a router local web page for easier configuration. But for now, you can check out the video demonstration!

Bulletproofing the install script
Spent two hours cooking my installer to perfection. But now we also have a logo!
What’s new
- Added several checks for sudo access, WiFi interfaces and required packages
- Added the uninstall script
- Made a video showcasing Pi Proxy Bridge at work
The time wasn’t logged, but I spent an hour trying to find free video editing software and blur out my ip address :p

Feature-full prototype + installation script
Added Xray Core and the routing rules so everything works together. Checked it with ifconfig.me. Also, I decided to automate the whole configuration process and made a bash installation script, which seems to work.
Learned a bunch of cool little bash things along the way, like set -e (which stops the script if an error occurs) or the difference between > and &>.

It works! (kinda)
Installed and configured hostapd (a tool for creating a hotspot)
Sounds simple but…
After setting up an access point, my phone did not connect and was just saying “Obtaining IP address”. Turns out, I also needed to install a DHCP server (dnsmasq) so it assigns different IP addresses to devices on the network.
But there’s no proxy right now, so…. more updates are to come

Architecture Sketch
Sketched out how my Pi Proxy Bridge works.
The Idea
Raspberry Pi (4B in my case) connects to my home wifi and shares its own hotspot at the same time. Anything on that hotspot gets routed through a proxy. My separate webcam (which needs a proxy to run, but can’t start one itself) connects to the hotspot and gets a proxied internet connection.
Profit.
Details
- Needs a dedicated USB wifi dongle
- No WireGuard or OpenVPN, because they often get blocked. Went with Xray-Core instead (vless, trojan, shadowsocks, etc.)
