Can anybody tell me which ports ping uses?
I would like to block ping requests on my routing and remote access server. And on our Cisco firewall in work.
Pings use the ICMP protocol and doesn't use ports like TCP or UDP. You could block all ICMP packets and that would certainly take care of it. It is possible to block only pings, but the way to do that depends on your firewall.
For example, iptables would be
... -p icmp --icmp-type echo-request -j DROP
