Dear community,
I have a problem with connecting to the VPN IPsec Client of a XG115. The Sophos Connect Client in the XG is running and configured with PSK. The User is created. Everyhting works fine from iPhone or iPad, equal if mobile data or wifi connected. But trying with a Windows 10 Client with the build-in VPN GUI in the same wifi fails with error "The L2TP connection attempt failed because the security layer encountered a processing error during the initial negotiations with the remote computer".
I already checked if the Service "IKE key generation module and AuthIP" (mentioned here https://community.sophos.com/products/xg-firewall/f/firewall-and-policies/96945/vpn-l2tp-issue-with-windows-10 ) is running. Second I already followed this guide https://community.sophos.com/kb/en-us/132253 but still it is not possible to connect.
A IPsec connection from the same Windows 10 Laptop to a Cisco Meraki is working fine, so I would say the Notebook is able to connect trough IPsec.
Is there someone who knows the problem? Thanks!
Edit: The Connection with the installed SOPHOS Connect Client and an imported tga file is running perfect. But the function build-in Windows 10 still is out of order.
