OK, are the connections to port 500 coming across the ISDN link?  If so
something on the other side of the isdn circuit is attempting to initiate
an IKE session.  You are using the "idletime-outgoing" and the
"idletime-incoming" directive in the isdnd.rc file?  or just
"idletime-outgoing"?

It sounds like this is getting into an isdn connection issue and I've
never setup isdn on a NetBSD box, however it probably would help if you
posted your isdnd.rc file.
