I've got a Windows 7 PC running a webservice accessing the internet through a standard router. I forwarded the required ports in the router accordingly and was able to use the service successfully from outside.
However, when I try to ping the PC, the request never succeeds. From my point of understanding, pings are performed using ICMP, which is not using ports, so I can't forward a port. Is there any way to get ping requests forwarded to and answered by the PC? (The router itself does not answer pings, apparently, nor do I want it to - I'd really prefer the PC to do that.)
Additionally, the PC does already answer pings from within the local network, but do I need to setup Windows so it also answers requests from outside?
