Pings are responses from the network card unless told otherwise. Sometimes devices will respond to ping even if they are in single user mode ie no O/S networking started.

My Belkin by default has firewall on but ICMP reply also on. So it will nicely steath port scans (drop packets rather than deny) but will respond to ping requests. I have turned off the ICMP reply so should now be pretty well stealthed.

Now usually on the inside (LAN) of the router is setup an address range like 192.168.1.0/24 (Belkin may use 192.168.2.0/24). This is a reserved IP range for internal networks and is not routable over the internet. The normal level of support rep on first contact probably does not have the know how to get around that (present company excepted).

Now if the firewall on the router is off where opted off or implicitly off because it is in access point mode (not routing) then they may be able to see your PC.
