Re: REJECT rules with tcp-reset.


just the reject rule works for me.  I don't need a rule on OUTPUT (even
though my OUTPUT policy, as probably yours, is DROP).

I don't bother with the --sport arg though, but I wouldn't expect that
to cause you a problem.

try your connection and check the rule counters (iptables -Lv) to make
sure this rule is actually getting hit.  Maybe you've made a mistake.
