MIKROTIK How to connect VPN through another VPN (PPPOE + L2TP + L2TP)?

Question

VPN

There are 3 different VPN L2TP, I need to do in 1 case that there is access to the Internet through double encryption, i.e. let's say vpn #1 connected to vpn #2 and the traffic went first through vpn #1, encrypted, connected to VPN #2, encrypted, and only then gave a response to the provider. And vpn #3 worked if vpn #1+#2 didn't work. And if vpn does not work at all, then there was no way out through PPPOE.

Answer 1

the option with VPN3 is solved by the route metric, you put more than the first 2 ... for the rest - xs

Answer 2

I think the easiest way is through routes:
IPvpn1 gateway=vpn2 distance 10 - vpn1 through vpn2
0.0.0.0/0 gateway=vpn1 distance 20 - all traffic through vpn1
IPvpn1 type=blackhole distance 30 - kill traffic to vpn1 if vpn2 is not connected.
0.0.0.0/0 gateway=vpn3 distance 40 - all traffic to vpn3
IPvpn2 gateway=ISP distance 50 - vpn2 via provider
IPvpn3 gateway=ISP distance 60 - vpn3 via provider
0.0.0.0/0 type=blackhole distance 70 - destroy all traffic

Answer 3

Er... PPPoE is l2. It does not apply to ip protocols and, accordingly, is not controlled by ip routing.
And shove PPPOE into L2TP - it won't work
