SoftEther VPN User Forum

I'm encountering a very strange result. My Mac can connect (via L2TP) to a SoftEther server hosted on AWS. My iPhone can't do it (via L2TP). I already tried multiple times to make sure the credentials are correct .


I also have a Window server that I have access to. For this, both my Mac and my iPhone can connect via L2TP to the Windows server. Is there any reason for this discrepancy?

Did you connect the Mac and iPhone to same NAT?
If so, the NAT have to support IPSec pass through.
