So what happens when the ARP entry on the peer's side needs to be
refreshed?

The peer will send an ARP request message, broadcasted using key2.
The client (which presumably cannot use key2) will then fail to
respond.

I see.

Just the same, what you're seeing is _not_ a dependency on DHCP.  It's
at best a coincidence.

What you're describing is an inability to receive broadcast and
multicast messages.  As I said before, if you can't receive those
messages, neither IPv4 nor IPv6 will function properly, and failures
will be both hard to predict and hard to diagnose.  Such a
configuration cannot be supported in any meaningful way, even if it
appears to "work" for some tasks.
