Blocking Aggressive Outbound Traffic with IPtables.
For starters, I’ve tested this on a test system that started out with NO iptables rules, and then moved on to an IPCop install (the vmware download from vmwarez.com…)
I’ve detailed previously one dilemma that I had with regard to my own cable connection which made me question how one could SAFELY host a wireless access point (in the clear) for guest web browsing, without allowing a wireless user to port scan the outside world/aggressively spread viruses/etc. Traditional firewall setups are typically oriented towards protecting the internal network. This post is an attempt to give an explanation of how to implement the idea put forth in this post.
