That's probably not a good idea.
It's probably worth looking at a plutodebug=all to see what happens when the
instances get mixed up. I would recommend rekey=no on the static end, and only
letting the ip changing end initiate.
You also mentioned a memory leak in another email, but I found no mention of
it elsewhere? Do you have more information?
