Multiple VPN IPSec access configurations

I am a newbie with Sophos firewalls having a XGS138 to configure and a Zyxel USG100Flex to migrate the configuration from.

One of the things I was not yet able to solve is how to configure the following remote client accesses together via VPN:

1. IPSec IKEv2 using a certificate for Win 11 clients and mobile phones (Samsung, iPhone)

2. L2TP over IPSec (IKE v1) for a Synology NAS

My current understanding is that I can have only 1 IPSec configuration with 1 profile (meaning either the one for IKEv2 or IKE v1). I tried to add the NAS connection separately under L2TP, but this hasn't been successfull so far. The online help doesn't provide any guidance either.

Is there any hands-on documentation how to solve the issue?
