I'm debbuging something weird here. Before I put together a full and sanitized error report, just a quick question: is anybody else seeing DPD to just stop working after a couple of hours, or is it just me & my setup?
I have some pre-3.9 -current (mid March or so) machines running some IPsec tunnels, and from the IKE dump it appears that after two hours both ends suddenly stop sending DPD R_U_THERE requests, even if the tunnel is totally idle (for example, if I down the interface connecting the hosts). The tunnnel never dies so the traffic for the other network goes into a black hole. Regards, Mitja
