<title>Introduction</title>
|
|
|
|
<para>Shorewall verions 2.2.0 and later include support for the ipp2p
|
|
match facility. This is a departure from my usual policy in that the ipp2p
|
|
match facility is included in Patch-O-Matic-NG and is unlikely to ever be
|
|
included in the kernel.org source tree. Questions about how to install the
|
|
patch or how to build your kernel and/or iptables should not be posted on
|
|
the Shorewall mailing lists but should rather be referred to the Netfilter
|
|
Mailing List.</para>

<title>Scope</title>
|
|
|
|
<para>In the following files, the "PROTO" or "PROTOCOL" column may contain
|
|
"ipp2p":</para>
|
|
|
|
<simplelist>

|
<member><ulink

<member><ulink
|
|
url="Accounting.html">/etc/shorewall/accounting</ulink></member>
|
|
</simplelist>
|
|
|
|
<para>When the PROTO or PROTOCOL column contains "ipp2p" then the DEST
|
|
PORT(S) or PORT(S) column may contain a recognized ipp2p option; for a
|
|
list of the options and their meaning, at a root prompt type:</para>
|
|
|
|
<programlisting><command>iptables -m ipp2p --help</command></programlisting>
|
|
|
|
<para>You must not include the leading "--" on the option; Shorewall will
|
|
supply those characters for you. If you do not include an option then
|
|
"ipp2p" is assumed (Shorewall will generate "-m ipp2p --ipp2p").</para>

|
<title>Example (assumes that you are running Shorewall 2.2.0 Beta 3 or
|
|
later):</title>
|
|
|
|
<para>Example 2 in the ipp2p documentation recommends the following
|
|
iptables rules:</para>
|
|
|
|
<programlisting>01# iptables -t mangle -A PREROUTING -p tcp -j CONNMARK --restore-mark
|
|
02# iptables -t mangle -A PREROUTING -p tcp -m mark ! --mark 0 -j ACCEPT
|
|
03# iptables -t mangle -A PREROUTING -p tcp -m ipp2p --ipp2p -j MARK --set-mark 1
|
|
04# iptables -t mangle -A PREROUTING -p tcp -m mark --mark 1 -j CONNMARK --save-mark
|
|
|
|
05# iptables -t mangle -A POSTROUTING -o eth0 -m mark --mark 1 -j CLASSIFY --set-class 1:12
|
|
06# iptables -t mangle -A POSTROUTING -o eth1 -m mark --mark 1 -j CLASSIFY --set-class 2:12</programlisting>
|
|
|
|
<para>These are implemented in the /etc/shorewall/tcrules file as
|
|
follows:</para>
|
|
|
|
<programlisting>#MARK SOURCE DEST PROTO PORT(S) CLIENT USER TEST
|
|
# PORT(S)
|
|
RESTORE:P - - tcp
|
|
CONTINUE:P - - tcp - - - !0
|
|
1:P - - ipp2p ipp2p
|
|
SAVE:P - - tcp - - - 1
|
|
1:12 - eth0 - - - - 1
|
|
2:12 - eth1 - - - - 1 </programlisting>
