my SUPER secure Raspberry Pi Router (wifi VPN travel router)

About this video

Chuck turns a Raspberry Pi into a travel router running OpenWrt, designed so his family can join public Wi-Fi at hotels, coffee shops or Airbnbs while all traffic exits through a VPN. He recommends a Raspberry Pi 4 for its built-in Wi-Fi and Ethernet plus speed, and notes you need two Wi-Fi interfaces in total: the built-in radio joins the upstream public network as a client, while a USB Wi-Fi adapter, which he says cost about 12 bucks, broadcasts the family’s private SSID; Ethernet joins the same local network. He flashes OpenWrt with the Raspberry Pi Imager, connects by Ethernet, sets a root password, and edits the files under /etc/config, backing them up first. The LAN address is moved off the very common default 192.168.1.1 to a custom private address, a WWAN interface is added to take an address by DHCP from the upstream network with Cloudflare and Google DNS, and a VPN client interface and firewall changes are prepared. After fixing the built-in radio’s wireless settings and joining his home network through the web interface to prove internet access works, he installs USB Wi-Fi drivers, brings the adapter up, and configures it as the access point with WPA2-style encryption and his own key. Finally he downloads a NordVPN OpenVPN UDP configuration, copies it to the Pi with secure copy, creates the client credentials and firewall rules through pasted commands, confirms in the web UI that traffic leaves via a NordVPN address, and adds a hotplug rule so the VPN restarts if its interface drops.

Key takeaways

• A travel router needs two Wi-Fi interfaces: one as a client to upstream public Wi-Fi and one broadcasting your own private network.
• OpenWrt on a Raspberry Pi 4 provides a full Linux router configured through /etc/config files or its web interface.
• Changing the LAN away from the default 192.168.1.1 and using trusted DNS are presented as basic hardening steps.
• Routing the whole Pi network through a NordVPN OpenVPN client makes every connected family device use the VPN automatically.
• A hotplug restart rule helps the VPN recover on its own when its interface disconnects while traveling.
