It might depend on the security profile of that PC. Also, the firewall has to have Layer 2 adjacency to the device in question. If there is another router in-between, it would not be able to scan those. If Symantec is configured exactly the same on more than one PC in that network, I would think it would affect more than one, yes.
The source address being the firewall though seems to indicate that it must be this though and not a random attacker from the Internet. It would have the attacker's IP address if it was, right?
