We're having some bad issues with the L2TP Client-To-Lan VPN and Apple Products.
Any iOS or macOS Client show the message that the L2-TP-VPN_server does not respond!

Windows Clients works fine, so anything should be configured right!

Seem like the Apple Device try to handle out with different DH Groups (Starts with 14,5,2) but the TL sends no answer?!

Any suggestions?
