View Full Version : [all variants] IPTables not saving drops

January 7th, 2011, 04:21 AM
I have been using IP tables to block particular IP addresses, so I thought. Then I looked at what the rules are, and it's only saving my last entry (I think). I have been using this to block:

iptables -A INPUT -s xxx.xxx.xxx.xxx -j DROP
Upon running

iptables -L -n
at the end of the INPUT chain I see:

DROP all -- xxx.xxx.xxx.xxx
where the IP address is the last one I blocked. Am I doing something incorrectly? What's the difference between -A and -I? I read the manpage and didn't see what should have been a big difference. I specifically am blocking IP addresses that are attempting to ssh in, but I have no problem generally blocking them from any port.

Thanks so much.
