Hi,

let me explain, i have 4 VPNs on my network, only 1 of them is connected over TP-Link, the other 3 are connected over Headscale, let me post a little drawing of my network topology

Main router is Router A, this one is the main headquarter, its where the Headscale server is which is the vpn server, Router B, C and D are on different locations, but only Router B and Router C are connected over the Tailscale network, Router D is over TP-Link IPSec VPN.

For each router i have manually created the routes so all 3 networks can communicate with each other, problem is i cant find a way to make all networks communicate with Router D network, only Router A and Router D networks can communicate because they are the ones that have the IPSec VPN between them, but Router B and C cant see Router D at all or vice versa.

I have tried to create routing tables on Router A which is the common ground for all my networks, but cant ping any device from Router B or C to Router D, so any ideas or suggestions i could try would love to hear them because i have run out of things to try

This is the IPSec VPN Status on Router A

And this one is for Router D
