I suggest you limit the incoming traffic to IKE service with GeoIP restrictions via Security Policy rules. It works perfectly for us.

See this thread where I describe a working solution for VPN using the free, native VPN client in Mac OS 15: https://community.zyxel.com/en/discussion/comment/70604

We're still running on USG series firewalls in multiple sites because FLEX H series is unstable and we didn't buy USG FLEX (non-H) series because they will eventually become EOL devices in the near future (IMHO) since ZyXEL will focus on the newest H line (that's what companies do).
