AZTCOFW / TECHNICAL GUIDE
Connection Fails with a Windows Client
If the IPsec layer appears to complete, but no L2TP traffic passes, it is likely a known incompatibility between Win- dows and the strongSwan daemon used on AZTCO-FW. There is currently no known workaround except to move the Windows system out from behind NAT, or to use a different style VPN such as IKEv2.
