USG Flex 200H: Unknown and unwanted VPN connection tries

e_mano_e

Using: USG Flex 200H / Firmware V1.32(ABWV.0)

I've configured IPSec VPN (IKEv2) to allow access behind the Firewall.

But no one was using a VPN connection in the past days.

But I'm seeing many VPN connection tries in the log.
All are from outside my home country (Germany).
I'm seeing tries from USA, China, Great Britain.

I've configured Geo-blocking to only allow VPN connections from a few countries (and the mentioned countries are not in this list) but I'm still seeing these VPN connection tries.

Here is a screenshot of the log:

Is there anything more I can do to avoid these connection tries?

Maybe my configuration for the Geo-blocking is faulty?

What's the best way to avoid these connection tries?

Thanks!

What can be done is use DDNS on the remote end so you know the IP and have firewall rule from WAN to Zywall source FQDN of the connecting DDNS
