IPSec no access to company network

[raiken]

Heya. I hope anyone can help me with this. Im pretty new to opnsense
I configured IPsec on opnsense and on a couple of mobile clients using the opnsense docs. I did not do anything else on the clients or the server. Only the stuff mentioned in the docs.
Mobile clients are linux/macos and the opnsense fw version is 21.1.2.

now establishing the connection from the clients works fine but none of the clients can access anything including the opnsense on the company network. Am I missing anything?
I'm really at a loss here since everything I seem to find on that topic is either "wan not working" or problems regarding site2site.

Thanks
