Question: How do I block someone using MAC or IP Address? (IPTables)
Splunking at my logs I found a long chain of unauthorized entries, already captured the IP's and MAC addresses, actually I use firestarter as my firewall solution but It doesn't allow me to introduce and Inbound "Black list" so I thought using IPTables...
How can I block this buggy guys trying to flood my server using iptables with MAC filtering (preferrable) or IP (last solution)? Please try to give me a full syntax and some little samples.
I'm still an trainee and training the hard way (by my own and continously reading my logs @.@) 'cause they don't teach this right now at my college (I'm a Linux geek Freshman XD), so please, patience about this question.
Thx for reading, I appreciate your answers & comments :D
