Comparing Soft Router Firmwares for using Tailscale Exit Node: OPNsense, pfSense & Openwrt

In my previous post, I mentioned that have a remote portal machine in my friend’s house where I use RustDesk to access into. However, in some use case, like access LAN resources and managing online services across multiple devices, the best practice is not using a remote desktop tool but having a VPN tunnel. Old Stories In the very early days, I used to use Hamachi to play LAN games like Counter Strike, Warcraft 3 and Minecraft with my internet friends.

Two month after flashing the Flint 2 GL-MT6000, I got its little brother GL-MT3000 in my hands as a powerful mini travel router runs stable build of OpenWrt. There are a few comparable routers in the same market, such as its older model GL-MT1300 v1 which is not very appealing price-wise; Cudy TR3000 v1 which is a direct competitor by its naming but has confusing variations that is not well supported by OpenWrt; and yet another older model Cudy TR1200 which is not available in the US. ...

During the prime day, my friend grabbed a GL.iNet Flint 2 (GL-MT6000) for a fair price, thanks to the slickdeals community.

USB Tethering a Portable Router into a Mobile WiFi Hotspot

Recently I came down to want a mobile hotspot when going out of home, something like Netgear Nighthawk M series, but able to flash custom firmware (OpenWrt/pfSense equivalents) and cheap. However, there is no such thing on the market even without budget consideration. So it has to be done with DIY, like USB tethering with a router.
