No, that's the entire point. If you change your network configuration -- which public keys (identities) are allowed to send what traffic, then this should not map to collided network signature. You're free to configure Windows to apply the same network profile and conditions to a variety of network signatures, of course. > For example, if a peer suffers a key compromise then its key will have > to change (and so thereby will the network GUID when calculated this > way) but all of the firewall rules and things like that should remain as > they are. Remap the new signature to the same network profile as before, in that case. In fact, remove the old signature from the trusted network profile, since now ostensibly it's compromised, given your premise. > It may help to add a config option We generally don't add nobs when there are sane secure solid defaults. > to allow the GUID for an interface to > be manually assigned a specific value.

Sounds like a "shoot yourself in the foot" situation. _______________________________________________ WireGuard mailing list WireGuard@lists.zx2c4.com https://lists.zx2c4.com/mailman/listinfo/wireguard
