Before I switched from dial-up to DSL, my results at ShieldsUp! were pure stealth, but now, while my ports still test as stealthed, my computer (or perhaps the DSL modem) is responding to pings (ICMP echo). Should I be concerned and, if so, how would I set up the proper configuration (ZAFree behind a Westell 2200 modem with an integrated firewall)? Also, would the modem's firewall be the reason why ZA no longer shows any logged events (blocks) even though it's set to do so? Thanks in advance.
