Hi there. I have a 4.2-S machine which lacks an upstream firewall to the net. While letting FreeBSD's ICMP_BANDLIM to do its work, I want to also be able to disallow users to send outgoing ICMP packets with malicious intent, while also allowing innocent users to be able to use ping(8)/etc. How would I set up my ipfw ruleset for this scenario, if possible? Also, what other concerns should I have regarding other net protocols to avoid incoming/outgoing attacks? Regards and thanks, Khairuddin.
