I only allow incomming ICMP from source ports 0, 3 & 11 and I allow all outgoing ICMP. I just do it to help security not as a stop-gap measure. To get back on the original poster's questions, It might not have been a DoS attack if it only happend once and rebooting helped it. It was more likely, some network problem.
