Hello,

I have a Windows 7 client that loses its IKEv2 connection with strongswan.

Strongswan logs is as follows :

May  2 14:31:09 casarrondo charon: 07[IKE] sending DPD request
May  2 14:31:09 casarrondo charon: 07[ENC] generating INFORMATIONAL
request 0 [ ]
May  2 14:31:13 casarrondo charon: 07[IKE] retransmit 1 of request with
message ID 0
May  2 14:31:21 casarrondo charon: 07[IKE] retransmit 2 of request with
message ID 0
May  2 14:31:34 casarrondo charon: 07[IKE] retransmit 3 of request with
message ID 0
May  2 14:31:57 casarrondo charon: 07[IKE] retransmit 4 of request with
message ID 0
May  2 14:32:39 casarrondo charon: 07[IKE] retransmit 5 of request with
message ID 0
May  2 14:33:55 casarrondo charon: 07[IKE] giving up after 5 retransmits
May  2 14:33:55 casarrondo charon: 07[IKE] unable to reestablish IKE_SA
due to asymmetric setup

The Windows 7 client on the other hand thinks that its VPN connection is
still alive but has no more connectivity.

Is this a known behaviour ? Is the issue on the server or the client side ?

kind regards,
Claude
