iptables -A INPUT -p tcp -s xxx.xxx.xxx.xxx -j REJECT --reject-with tcp-reset

if i want to block access?

i just didnt understand when i added a 'new rule' to block that ip address via the linux gui
why it still showed up in the log file.
do the ip's still show up in the log when they are set to be denied all access? could it be a spoofed ip?
