That doesn't work when the interface IP address changes, because
the current code doesn't watch for interface changes, drop old
interfaces from the list, add new ones as they come along, etc....
With the current code, your solution will only work when the
interface keeps the same IP address, and your connectivity is only
interrupted. If you're behind a NAT/router which gets its IP address
changed but your local hosts keep theirs, you might still have
issues. Certainly, you'll be likely to have to drop and re-add.
As I said, we're working on fixing this.
