Block some of it.

I let my router forward all ICMP to my own computer. The firewall on my pc only allow's it for eiter the IP of my school a number of my friends and inside the network. Everything else is blocked.


The reason I allow school is because I want to be able to check up on my computer from there. The friends for the same reason, and so they can check up on it for themselves.

Basicly I think ICMP is a good thing. People getting to know my os isn't really something I think is a problem in my case. And you can alway's only allow a certain amount of people in...

If your admin of an important network or company then things change though.
