Blocking IP's with IP Tables blocks actual traffic
I get people trying ssh attacks against my computer and I have tried blocking their IP addresses with the firewall in ip tables and it starts to block legitimate traffic. At one point it was blocking traffic going out of the computer. All I did was set up a rule that would drop all traffic coming from that ip or blocks of ip's. Any ideas?
i haven't looked at your iptables rules, cuz honestly redhat's way of doing rules confuses the heck out of me, but to block some IP which is bugging you just execute something like this:
Code:
iptables -I INPUT -s xxx.xxx.xxx.xxx -j DROP
where xxx.xxx.xxx.xxx is of course the IP you want to deny all access to your box... this rule when executed from the command line should work no matter what your other rules are doing, as the "-I" sends it to the top of the chain...
