Hi,
Thanx for the response, albeit most of them pinned only Ping as the danger
in allowing ICMPs into the network. Its true that by default the firewall
should block all ICMP messages. But my private network environment is very
small and simple. I have no routers inside. A simple LAN. So can ICMPs,
other than Ping do any damage if they r given unrestricted access ? I looked
at a lot of materials on the internet but could not get any convincing
replies that any message other than Ping, could do any substantial damage
into my network.
Does anybody has any other thoughts or experienced problems with any other
ICMP messages ?
Thanks in advance
Sujeet
