Can someone advise me where the control is to turn on or off whether a local computer responds to a ping over the internet (ICMP echo?).
Check out Norton Firewall Traffic Rules for ICMP rules.
Note x box'd grey and box'd in blue and not x'd box's.
I think by default pings are stealth.
and check your router documentation
FWIW ~ my router firewall at maximum.
A hardware firewall (router) is what makes you stealth on the Internet. It should handle pings from any source.
