IKEv2 android e ios

spatai

Hi, I followed this guide step by step:  https://support.zyxel.eu/hc/it/articles/8805317185298-VPN-IKEv2-con-chiave-precondivisa-su-dispositivi-mobili-invece-di-L2TP#h_01HB6CZ4685VCSJ22W1NW2J98E
but I can't log in to VPN, when I try to connect for example from Android, I get a message saying "connection not secure" and then nothing happens, can you help me please? Thank you

Hi @spatai,

Thanks for the screenshot. I did a local test with my Android 14 smartphone. Following the link you mentioned did not have the "not secure" message. Please help to check if this VPN profile is an old profile that uses L2TP protocol, and try to create a new VPN profile with IKEv2/IPSec with PSK.

Hi @spatai,

I found the issue is due to the Android didn't support big capital in the pre-shared key column. I can reproduce this issue in my lab. I fix this issue if I change the pre-shared key to small capital for all letters.

Please help to change the pre-shared key on your firewall > VPN gateway settings.

Hi @spatai,

I would like to clarify with you:

1. What is your Android version?
2. Could you share the screenshot of the error?

Firewall: ATP 100

Android: 14

Thanks

Thanks… I have already done several tests by recreating the new VPN connection, but I receive the same error, to make sure that I have configured everything correctly, IP or FQDN of the firewall's WAN interface, is public ip right?

Hi @spatai,

Public IP is correct.

So I configured all correcty by guide, but I can't understand why it doesn't work, What other tests could I do or an alternative route? Thanks
