23) Shorewall now includes 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.
|
||||
|
||||
In the following files, the "PROTO" or "PROTOCOL" column may
|
||||
contain "ipp2p":
|
||||
|
||||
/etc/shorewall/rules
|
||||
/etc/shorewall/tcrules
|
||||
/etc/shorewall/accounting
|
||||
|
||||
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:
|
||||
|
||||
iptables -m ipp2p --help
|
||||
|
||||
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").
|
||||
|
||||
24) Shorewall now has support for the CONNMARK target from iptables.
|
||||
See the /etc/shorewall/tcrules file for details.
