But it wouldn't be that hard to add the ability to add the same allowed-ips entry to multiple peers, and have WireGuard duplicate the message to all of them. It's not complicated in theory, but I wonder if this would be genuinely useful, and whether or not it'd open up a wormhole of potential issues. Thoughts? Jason
