iptables: blocking multiple ports with one rule.
Asked by
daniel CURTIS
Hi. I have one short question related to iptables and ports. There is many FAQ's, HowTo's on the internet, but I'm still confused. So, here is a question; let say, that I want to block port range from 100 to 200. Which rule is correct for doing this?
,-----[ block multiple ports ]
| 1) iptables -A INPUT -p tcp --match multiport --dport 100:200 -j DROP
| 2) iptables -A INPUT -p tcp -m tcp --dport 100:200 -j DROP
`-----
Sorry for such naive question. Best regards.
