Setup for second OpenWRT One as a VPN travel router

Installing and Using OpenWrt
1

I have an OpenWRT One at home as my router, setup for DDNS and WireGuard.

Now I have bought a second OpenWRT One that I want to use as a travel router. It should work in the following way.

  • The travel router provides a WLAN (and LAN) for my devices, when I am traveling.
  • It uses either Ethernet or a WLAN (given at my actual location) for WAN.
  • If WAN is connected successfully, the travel router should establish a VPN connection via WireGuard to my router at home. This does not have to be automated. Activating that tunnel manually by myself would be completely fine.
  • Every WAN traffic of my devices that use my travel router should be routed over the VPN tunnel to my router at home, after the VPN connection between the two routers is established.

My main problem (at the moment) is that I don't know how to setup my travel router as a peer for my router at home. I want the travel router to be a WireGuard client for my router at home. It should not provide any additional own WireGuard VPNs.

You create an extra peer on your WireGuard "server" and import that on your travel router which functions as a WireGuard client
For some detailed instructions see:

You might also want to look into using travelmate:

For easy connections to wlan hotspots

Thank you very much. :slight_smile: :+1:

I will work through that and then give some feedback here, if I won't have any more questions during the setup.

Let me know if you want any specific help but if you installed WireGuard as outlined in the guides you will also have the packages to import and export WireGuard configs which make setting up peers very easy.

Okay, I read the guides and have one general question so far.

Travelmate seems to be what I am looking for, but is it only for wireless WAN connections? What if I use Ethernet for the WAN connection?
Does Travelmate work in combination with mwan3?
