tinc - Dec 2003 - routing bug?

Hi,
	Exactly I don?t know if this is a bug or not. I have a LAN with one switch
and one hub.
Yesterday I was in vpn with a customer (vpn tunnel 1.2.3.0 subnet 255.255.0.0)
when a colleague has attached his notebook that was set with the network
1.2.4.0. I suppose that his notebook has sent a lot of broadcast messages
on the network, infact my vpn connection was broken quite immediately!
When he set his notebook correctly for our LAN I could establish a new VPN
tunnel.
My questions are:
1-	The problem is the HUB?
2-	If not this is a potential DOS bug?

                           Thanks dario

The problem is the wrongly configured notebook. You've already seen it
can work as a DoS, but I don't think it's because of a bug in tinc.
