Hi @b.gorsky,
Please refer to the following template files, I have tested and successfully established a IPsec VPN connection, I’m using RV50X and MP70.
RV50X_client.xml (111.6 KB)
MP70_server.xml (125.0 KB)
Additionally, please refer to the following topic to see if it is helpful: IpSec Tunnel between 2 RV50X
Thanks,
