I am having trouble while connecting a Windows VPN client to Strongswan using Machine certificates. I am following the wiki:
Would appreciate any pointers to resolve the issue.
Issue: Windows client is not connecting
As per wiki, have created CA and signed the Strongswan server and Windows client req.
The certificates and private keys are kept at proper locations as specified.
update-ca-certificates is done to update the trusted certificates on the linux machine running strongswan server.
On the windows side, both CA certificate and windows client certificate is imported. Both the certificate shows "This certificateis ok"
When the client initiates connection, I see strongswan sending a cert request for the CA certificate.
The CA, server and client are as follows:
CA: "C=CA, ST=ON, L=Miss, O=iS5, OU=SW, CN=ca at 10.10.5.1, E=ca at is5com.com"
Strongswan server: "C=CA, ST=ON, L=Miss, O=iS5, OU=SW, CN=server at 10.10.5.1, E=server at is5com.com"
Win client: "C=CA, ST=ON, L=Miss, O=iS5, OU=SW, CN=win at 10.10.5.7, E=swin at is5com.com"

I was expecting a windows cert request. Instead I see a CA Cert req. Am I missing anything?
