HTTP requests are sent over TCP, so try a REJECT with TCP reset instead. |
| 17 |
Something like this should do the trick, since the connection would be reset |
| 18 |
more or less instantly avoiding the timeout: |
| 19 |
|
| 20 |
iptables -A INPUT -s xxxx -p tcp -j REJECT --reject-with tcp-reset |
| 21 |
iptables -A OUTPUT -s xxxx -p tcp -j REJECT --reject-with tcp-reset |
