A feature. The AllowedIPs controls which IP addresses will be routed to
that peer. They refer to addresses inside the tunnel. So depending on
your setup you'd specify the single IP you assign each peer, or possibly
any subnets behind that peer you want routed through the tunnel.

Changing IPs *on the outside* of the tunnel will be accepted
automatically. The Endpoint specifier is only the initial address; if a
device changes its IP, it'll just keep sending packets from the new IP,
and because they are authenticated by the crypto, the other peer will
accept them and change its notion of what IP the other peer is
reachable at automatically. So as long as only one peer changes its IP
at a time, roaming mostly just works :)
