Assistance with routing(?) & forwarding needed

Hello everyone :slight_smile:

I’m strugling a bit with setup shown on the “diagram”.

2 sites with Mikrotik routers “Main” 88.88.88.88 and “Satelite” 99.99.99.99 connected by Wireguard Site2Site tunnel (working just fine both directions)
On top of that on between “Main” 88.88.88.88 and “3rd party” 77.77.77.77 router there is an IPSec Site2Site connection establised (working just fine)

What I wish to achieve is to allow every one from 192.168.10.0/24 network (“Satelite” 99.99.99.99) to access 192.168.5.0/24 on “3rd party” 77.77.77.77.
Where I should start?

What do you think?
Traffic arrives at the main router, do what you have to do to get it to enter the ipsec tunnel… and be accepted at 3rd party router when it exits the tunnel and make sure it has a path back to the main router etc…

So should the title of your thread, be Learning IPSEC???
