I had this working a few months ago where I had two VPNs on my 100D. An L2TP/IPSec VPN for native Windows clinents and a IPsec VPN for Mac native clients. Since El Capitan and update 10.11.4 changed the default DH Group to 14, I can not run both VPNs anymore. After adding DH Group 14 to the IPSec VPN (which is used for both Mac and Android native VPN clients), L2TP/IPSec VPN Clints try to connect as regular IPSec VPNs. If I try DH 14 for only L2TP, the connection shows up as trying to connect to N/A (keeping DH Group 2 on IPSec for Android VPN).
Also, no matter what I try and config using only L2TP/IPSec (DH Group 14, both Mac and Windows connect using native clients) the Android Native L2TP/IPSec will not connect.
All config is with PSK and AES256-SHA1. I have tried with 3DES-SHA1 and 3DES-MD5, both have same results.
Any Suggestions?
