what sort of firewall drops packets on localhost ?!?
yahoo.com is probably a poor choice of targets, as its a widely distributed group of servers, and you likely will be pinging different servers at different times, maybe even in different parts of the world. I would instead suggest using a target at your ISP or backbone provider.
btw, dropping 'all icmp' is bad practice. Internet Control Message Protocol is used for a number of things, including informing applications when a host or port is not accessible. if you drop this, you instead hang for minutes waiting for a response instead of quickly getting back a 'target {host|port} not reachable' error.
anyways, if you drop all ICMP, you won't get any pings from anywheres.
