I am trying to connect the Windows Embedded Handheld 6.5 Professional to a L2TP/IPSec VPN server with given configuration:
Remote Gateway : xxx.xxx.xxx.xx
Authentication Method : Pre-shared key : xxxxxxxxxxxx
Mode : Aggressive
Phase-1 Proposal: aes128-sha256
DH Group : 5
Phase-2 Proposal: aes256-sha1
PFS: enable
DH Group: 5
User-name: xxxxxxxxxx
Password: xxxxxxxxxx
Every time i try to connect, it gives error of wrong user-name and password. I have successfully used above mentioned details to connect from Desktop.
I have tried the following:
Does the device support SHA2? Windows Mobile devices (Windows Embedded Handheld) do not support SHA2 before a defined AKU (35) has been implemented within the firmware: https://support.microsoft.com/en-us/help/2986556/windows-embedded-handheld-6-5-does-not-support-sha2.
