Hi all,
I'm trying to connect using my iphone to a softether server.
I'm setting up a vpn connection on iphone using the GUI. Setting the vpn type to IPSec.
When starting the vpn connection, I get the error:
"The VPN Server did not respond"
On the server side I'm getting the error:
"There are no acceptable transform proposals from the client for establishing an IKE SA."
Using the exact same configuration on iOS but using L2TP instead is working fine. I guess this is a very specific problem related to the iphone
I have iOS 9.3.4
Here are the server logs:
"
2016-08-25 16:11:26.665 IPsec Client 11 (xx:500 -> xx:500): A new IPsec client is created.
2016-08-25 16:11:26.665 IPsec Client 11 (xx:500 -> xx:500): There are no acceptable transform proposals from the client for establishing an IKE SA.
2016-08-25 16:11:29.950 IPsec Client 12 (xx:500 -> xx:500): There are no acceptable transform proposals from the client for establishing an IKE SA.
2016-08-25 16:11:36.936 IPsec Client 11 (xx:500 -> xx:500): This IPsec Client is deleted.
"
Any ideas what is happening?
Does anyone know for a fact that SoftEther IPSec is working fine on iOS??
Cheers

Re: iOS9 is not working with IPSec
I found the problem.
I was using IPSec on iPhone, while softether supports L2TP over IPSec.
Using L2TP protocol on the ipone solved the problem
Follows question:
Can I get a pure IPSec configuration running on softether? (i.e. without L2TP, for example like in strongswan)

Re: iOS9 is not working with IPSec
SoftEether support only L2TP/IPSec.

Re: iOS9 is not working with IPSec
Erm... If you use L2TP without IPSec then, if I understand this right, the tunnel between your iPhone and the VPN server is unencrypted and as such, not secure?moatazelmasry wrote: ↑Mon Aug 29, 2016 10:11 pmI found the problem.
