SoftEther VPN User Forum

Please have a look at the server logs of SE and add them here, specifically

server_log/

Also if you can, pleas recompile SoftEther using:
make DEBUG=YES
Then start SE as following:
./bin/vpnserver/vpnserver execsvc

Then initiate a connection from your windows client, then save the debug output into a file and paste it here as well

Cheers

IPsec server and client can't work on the same machine.
Please try another host as client.
