[Openswan Users] sending notification PAYLOAD_MALFORMED

[Paul Young]

Hi all,

After rebooting one side of my Openswan setup without changing config and
so on I am getting this error and cannot create a tunnel anymore.

The reason I rebooted the host is I applied a bunch of firmware updates to
the hardware.

Sep 23 18:33:23 lobster pluto[38968]: "conn"[11] <outside IP address> #55:
next payload type of ISAKMP Identification Payload has an unknown value: 23

Sep 23 18:33:23 lobster pluto[38968]: "conn"[11] <outside IP address> #55:

I have triple checked the PSK and it appears to be fine. What am I missing?

Thanks,
Paul
