I'm not an expert IIRC every router used by a packet makes ttl--, so if the packet had tt=3 and passed trhu 3 routers, it will have now ttl=0 And should be droped, I think, but over LANS there is a common problem that the packets reaches even if has ttl=0, so, if the packet comes from your network, no worry.
