With IPsec, the subnets on both sides are explicitly negotiated, and you
can forward traffic matching these subnets. Associated routes are
installed automatically by strongSwan, but they are just used to
properly find the associated tunnels, not to enforce policies.

Your config already has a rightsubnet=, so you can access
these destinations through the tunnel. You probably want a leftsubnet as
well to define the subnets for your end; if omitted, you're limited to
your "external" IP you communicate with IKE.

[1] is certainly a good read to better understand forwarding in
