Are there any security issues for allowing a firewall/router to respond to Ping from the internet? -Paul Kurczaba
Yes. It would not be preferable for you to allow your firewall/router to respond to pings from the internet. Someone running a wide-scale scan of internet computers for possible attack targets would quickly be made aware of your obvious internet presence and you could become a target for attack. This wouldn't be such a big problem provided your firewall/router was well-configured with security in mind. If there is no overwhelming reason for allowing your device to respond to pings then it shouldn't be configured to do so. It is simply calling too much attention to your systems and their possible vulnerabilities. Well anyway, that's my quick 2 cents on the matter. I'm sure others will share theirs too.
