IPSec VPN disconnected

I have tried to set up a VPN connection between a Fortigate 90D and a Windows 10 native client. According to the logs, the negotations are correct but the connection is dropped.

This is my config:

config vpn ipsec phase1-interface     edit "VPN_Windows"         set type dynamic         set interface "wan2"         set keylife 28800         set peertype dialup         set proposal aes256-md5 3des-sha1 aes192-sha1         set dhgrp 2         set usrgrp "VPN users"         set psksecret ENC DJeIczJZqdMFw...     next end

 

config vpn ipsec phase2-interface     edit "VPN_Windows"         set phase1name "VPN_Windows"         set proposal aes256-md5 3des-sha1 aes192-sha1         set pfs disable         set keepalive enable         set encapsulation transport-mode         set l2tp enable         set keylifeseconds 3600     next end

 

I setup the VPN connection on Windows 10, setting the preshared key correctly.

 

These are some lines you may find useful in the FG log:

 

ike 0:70f373750b2a2064/0000000000000000:50: SA proposal chosen, matched gateway VPN_Windows

ike 0:VPN_Windows:50: PSK authentication succeeded ike 0:VPN_Windows:50: authentication OK

ike 0:VPN_Windows_0:50:VPN_Windows:26: matched phase2

 

And then this:

ike 0:VPN_Windows_0:50: recv IPsec SA delete, spi count 1 ike 0:VPN_Windows_0: deleting IPsec SA with SPI d6050872 ike 0:VPN_Windows_0:VPN_Windows: deleted IPsec SA with SPI d6050872, SA count: 0 ike 0:VPN_Windows_0: sending SNMP tunnel DOWN trap for VPN_Windows ike 0:VPN_Windows_0:26: del route 190.19.57.99/255.255.255.255 oif VPN_Windows_0(67) metric 15 priority 0 ike 0:VPN_Windows_0:VPN_Windows: delete

Just a proposal:

in former times Win VPN used a combination of keylifeseconds and keylifebytes. You can activate that both are observed in the FGT. IIRC it was 2.5 MB = 25000000 bytes.

Did you find any solution for this problem? I'm with the same issue since I upgraded to 5.4.

 

My clients are coming with UDP_ENCAPSULATION_MODE_TRANSPORT_RFC3947 encapsulation and it looks Fortigate is expecting UDP_ENCAPSULATION_MODE_TRANSPORT.

Hi, did you solve the problem? I have some issue with client's Android 5 device.

Not yet. I opened a ticket with Fortinet but didn't have an answer yet, as usual.
