+.Sh BUGS
+.Nm
+will respond too slowly to ARP requests for some applications. In 
+order to ensure that it does not claim existing IP addresses it will send two
+ARP request and wait for a reply. This slowness affects the \fBnmap\fR network
+scanning tool, and possibly others, which uses by default ARP when scanning
+local networks. The answers from 
+.Nm
+will come after the tool has timeout waiting for the ARP replies and,
+consequently, IP addresses claimed by 
+.Nm 
+will not be discovered.
+.Pp
+Additionally, 
+.Nm
+sends the ARP replies to the broadcast address of the network and not to the
+host that send the ARP request. Some systems and applications (notably
+\fBnmap\fR) will not handled these requests and expect directed ARP replies
+(i.e. targeted specifically to the host that sent the request and not to the
+network)
