7800X and L2TP+IPSec VPN problem

[Zanda1]

Hi,

I have the Billion 7800X and I've set up a L2TP + IPSec VPN server. I am unable to connect to it from a VPN client.

It has the latest version of the firmware, version: 2.32e
I've set up a PPTP VPN server and it works perfectly, however if I set up the L2TP + IPSec VPN server by following the manual it doesn't work. I set up an anonymous IPSec and enabled L2TP over IPSec. The VPN Account was set up and tunnel was enabled and remote access connection type. The L2TP Server was enabled, the Wan Interface is "default or IPSec tunnel", authentication type is Chap.

When I try to login with Android v4.2 and 5 I get the following in the router log:
sending encrypted notification INVALID_ID_INFORMATION to XXX.XXX.XXX.XXX:51409
the peer proposed: XXX.XXX.XXX.XXX/32:17/1701 -> 10.38.127.203/32:17/0
cannot respond to IPsec SA request because no connection is known for

When I try to login with Windows 10 I get the following:
ignoring unknown Vendor ID payload
ignoring Vendor ID payload [MS NT5 ISAKMPOAKLEY ]
received Vendor ID payload [RFC 3947] meth=115, but port floating is off
received Vendor ID payload [draft-ietf-ipsec-nat-t-ike-02_n] meth=106, but port floating is off
ignoring Vendor ID payload [FRAGMENTATION]
ignoring Vendor ID payload [MS-Negotiation Discovery Capable]
ignoring Vendor ID payload [Vid-Initial-Contact]
ignoring Vendor ID payload [IKE CGA version 1]
initial Main Mode message received on 192.168.1.1:500 but no connection has been authorized with policy=PSK

Thanks
