Is there any complete guide can help me setup my L2TP/IPSec server? Thanks!

Apple has removed PPTP VPN in their latest IOS update. So if you are using that you have to migrate over to Ipsec or other encrypted VPN technology.

I menaged to do Mikrotik configuration for L2TP. Everything worked with iOS 10.0.2 but yesterday afer update 10.0.3 is stopped.
Does anyone has the info what they changed and what needs to be done in mikrotik to get this working.
PS: Everyone in my company which are still on 10.0.2 can connect without problem.

If its ipsec part that fails then you can see where exactly is the error in ipsec debug logs.

I have gor problem with mikrotik ip sec for Apple ios
the log :
Failed to get valid proposal
Failed to pre process ph1 packet(side :1,status : 1)
phase1 negotioation failed

what shall i do ?
