<title>Problems with RH Kernels after 2.4.20-9 and REJECT (also applies to

2.4.21-RC1)</title>

<para>Beginning with errata kernel 2.4.20-13.9, <quote>REJECT
|

--reject-with tcp-reset</quote> is broken. The symptom most commonly seen

is that REJECT rules act just like DROP rules when dealing with TCP. A

kernel patch and precompiled modules to fix this problem are available at
