) mikrotik (10.0.0.2/24) VPN is configured on it at 172.16.0.1/24
I will give an example of a problem
If from PC 172.16.0.25 try to access the web service 10.0.0.26 (The gateway for this PC is 10.0.0.1)
We get an error.
And vice versa from PC 10.0.0.26 (The gateway for this PC is 10.0.0.1) try to access the web service 172.16.0.25 (gateway 172.16.0.1) We get an error.

Answer 1

on mikrotik add routes to your vpn-s on juniper via juniper

/ip route add dst-address=10.0.1.0/24 gateway=10.0.0.1
/ip route add dst-address=10.0.2.0/24 gateway=10.0.0.1
/ip route add dst-address=10.0.3.0/24 gateway=10.0.0.1

On the juniper, respectively, there must be a route to 172.16.0.0/24 through 10.0.0.2
Each computer must have a gateway from its subnet.
