My goal is to have all clients that connect to a specific WLAN network, let's call it N5, connected to the internet via a VPN Tunnel to ExpressVPN. I have other routers that can successfuly establish the VPN tunnel connection to ExpressVPN using L2TP and assume that side of equation works in general.
To get this running I have configured:
- A DHCP pool
- A VLAN (5) using that pool
- L2TP tunnel configuration (there also is L2GRE config that I can't seem to be able to delete)
- A WLAN using VLAN 5
All is working fine and as designed with the tunnel option in the WLAN config turned off. As soon as I turn on Tunnel Mode, it doesn't work anymore.
A few questions:
- Is what I am trying to achieve feasible in general, or is the tuneling meant for other purposes only?
- What is the besr way to see if the tunnel is up and if not, what errors are associated with the attempt? I can see errors in the debug log if I switch from L2TP to L2GRE, but I can't see anything in L2TP mode.
- Any recommendations on what I am doing wrong / should be doing instead?
