Given the large user base, we plan to lease IPs automatically using a custom upper layer service before users can connect, but we can not seems to find a proper opportunity to reclaim those IPs. Once allocated, it seems wireguard assumes the client can use the IP forever, since there is no explicit disconnection. What's the proper way to deal with large number of IPv4 clients? (We're aware of the wg-dynamic project, but it seems it's IPv6 only.) Regards.

It will use a link local IPv6 address for communications between client and server daemons. Maybe this can explain the misconception that it would be handling IPv6 addresses only? _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard ^ permalink raw reply [flat|nested] 3+ messages in thread

Umm, no. A client can only use addresses assigned to it. Thus if you give the address to another client, packets from the original client using that source address will be discarded. -- -- Matthias Urlichs _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard ^ permalink raw reply [flat|nested] 3+ messages in thread
