iptables icmp limits
could someone tell me what they would recommend as a sensible ICMP type 8 (echo-request) limit, for a router box that serves 4 windows XP machines?
1/s? 2/s? burst value? ... i dont want the XP boxes' service to be affected by the limit...
Also, does the limit affect any host that matches the rule, or EVERYONE.. ie, would the box only be able to accept 1 ping per second from any one host, or 1 ping per second in total?
