Hello, I have configured a L2TP with IPSEC on my RUTXR1RUTX_R_00.07.01.2). But no client can be etablished a vpn connection. I have tried with a Windows 10 and a iPhone device. In the logs there are some issues present, when I try to connect. I have tried some other encryption algorithm and authentication on phase 1 and 2. Also I have tried to set it to IKEv1, but no success. At least I rebooted the complete RUTXR1 without any success.

Hello,

I would like to suggest reviewing our L2TP over IPsec guide: https://wiki.teltonika-networks.com/view/Connecting_to_the_office_network_remotely_from_your_home_via_VPN_(L2TP_over_IPsec)_using_RUT9xx

Please double-check your settings and configuration process and inform if your PC will be able to connect to RUT.

Regards.

Hello,

I found the reason for the issue. If I set the IPSEC configuration to ikev2, no connection from Windows 10 client can be etablished. If I set it to ikev1 there is no issue and the connection can be etablished.

But another issue with iOS devices - there can not be with any settings connect. Is this a bug? iPhone says "vpn server is not responding"

Hi,

I can also confirm that iOS devices (iPhone running iOS v15.4) cannot connect via native L2TP/IPSec VPN client to RUTX11 (configured as VPN server). The error displayed on the phone is always the same: "VPN server is not responding"

RUTX11 is currently running v07.01.4 (latest) but the issue was also present in all previous v07.xx versions. It is important to note however that RUTX v06.x had no such VPN connection problem.
