This is at least a limitation in Android itself:
https://developer.android.com/reference/android/net/VpnServi...
"There can be only one VPN connection running at the same time. The existing interface is deactivated when a new one is created."
Note this is not about routing some traffic to the VPN and other traffic to the clear net. This is about running two VPN connections simultaneously.
On a linux box, is it possible to run tailscale/wireguard as an exit node along with Forti vpn?
Aka what I want to achieve is (my-machine + tail/wireguard) --> (server with tailscale/wireguard + forti vpn) --> Corporate network. So wireguard or tailscale to receive traffic and forward it through forti.
Or another option (my machine fortivpn over tail/wireguard) --> (server as exit node) --> corporate network
Rather than using the official forticlient I am using https://github.com/adrienverge/openfortivpn. It has some options to configure custom pppd/routes/dns etc if necessary, which I have not touched as I don't know enough :P DNS resolution is not important for my usecase, only traffic.
Yea on Linux I can run 10 different VPNs (or 10 wg peers) no problem, this limitation of Android is super annoying to me. I think OPs solution is quite a good one for Android users.
Fair enough. I haven't used an Android device since 2017... Do people have these issues on iOS too?
On Linux, I have no problem running either bare wireguard or tailscale alongside Forticlient. On Windows and macOS it's a bit more janky, specifically the DNS resolution, but I don't daily drive these platforms so I may be missing some kind of knowledge to fix this.
