# This is for ipset protocol 4 (ipset v4.2). If you have a later version
|
|
|
|
|
# of ipset try to use the iptables-ipset-proto6.conf as it does some things
|
|
|
|
|
# nicer.
|
|
|
|
|
#
|
|
|
|
|
# This requires the program ipset which is normally in package called ipset.

# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0 kernels.
|
|
|
|
|
#
|
|
|
|
|
# If you are running on an older kernel you make need to patch in external
|
|
|
|
|
# modules.
|
|
|
|
|
#
|
|
|
|
|
# On Debian machines this can be done with:
|
|
|
|
|
#
|
|
|
|
|
# apt-get install ipset xtables-addons-source
|
|
|
|
|
# module-assistant auto-install xtables-addons
