Can I tell if traffic was sent by a firewall and not remote host?

If I look at a trace, is it possible to tell whether a frame was sent be a switch or a firewall and not by one host or the other? Like if a socket it moving along and suddenly one of the hosts sends a reset, how do I know if I'm the victim of deep packet filtering by a switch? Is there something at the TCP or ethernet level that's a clue?

thanks
