HTTP requests are sent over TCP, so try a REJECT with TCP reset instead. Something like this should do the trick, since the connection would be reset more or less instantly avoiding the timeout: iptables -A INPUT -s xxxx -p tcp -j REJECT --reject-with tcp-reset iptables -A OUTPUT -s xxxx -p tcp -j REJECT --reject-with tcp-reset Regards //Tony -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iD8DBQFIzM9mJDzv6DN+QUkRAuQUAJ9ddYprAGKNHHSHvyTugu0HkKmB6gCgv87O IKaE8FG5B8RVSrNPFVYCpyg= =PKLJ -----END PGP SIGNATURE-----
