Problems Corrected in Shorewall 4.2.0 Beta 2
|
||||
Problems corrected in Shorewall-perl-4.2.0 Beta3.
|
||||
|
||||
1) When 'norfc1918' was specified on an interface with an RFC 1918 IP
|
||||
address, the compiled script would terminate without changing the
|
||||
state of the firewall. Under these circumstances, the script now
|
||||
issues a warning message and continues.
|
||||
1) The 4.2.0-Beta2 change which defers setting up ip forwarding until
|
||||
the rules are in place did not handle the 'restore' command
|
||||
correctly. So if '-f' is specified to the 'start' command and there
|
||||
is a saved configuration, the setting of ip forwarding will not be
|
||||
changed.
|
||||
|
||||
Problems Corrected in Shorewall-perl 4.2.0 Beta 2
|
||||
Other Changes in Shoreall 4.2.0 Beta 3.
|
||||
|
||||
1) Except in /etc/shorewall/hosts, ipset names may now be preceded by
|
||||
'!' to specify that matching IP addresses are not members of the
|
||||
set.
|
||||
|
||||
Problems Corrected in Shorewall-shell 4.2.0 Beta 2.
|
||||
|
||||
1) When DYNAMIC_ZONES=Yes, certain configurations would produce an
|
||||
invalid /var/lib/shorewall/chains file at run-time. The invalid file
|
||||
contents resulted in errors during processing of the "shorewall add"
|
||||
command.
|
||||
|
||||
Other Changes in Shoreall 4.2.0 Beta 2.
|
||||
|
||||
1) A 'save' extension script is added. The script is run after
|
||||
iptables-save has completed successfully.
|
||||
|
||||
The 'load' and 'reload' commands copy the save script (if any) to
|
||||
/etc/shorewall-lite/ on the remove firewall system. The 'export'
|
||||
command copies the file to the same directory as the 'firewall' and
|
||||
'firewall.conf' scripts.
|
||||
|
||||
I have the following commands in my 'save' script:
|
||||
|
||||
[ -s /root/ipsets.save ] && cp -a /root/ipsets.save /root/ipsets.save.backup
|
||||
ipset -S > /root/ipsets.save
|
||||
|
||||
These commands complement my 'init' script:
|
||||
|
||||
qt modprobe ifb numifbs=1
|
||||
qt ip link set dev ifb0 up
|
||||
|
||||
if [ "$COMMAND" = start ]; then
|
||||
ipset -U :all: :all:
|
||||
ipset -U :all: :default:
|
||||
ipset -F
|
||||
ipset -X
|
||||
ipset -R < /root/ipsets.save
|
||||
fi
|
||||
|
||||
Those two scripts allow me to save and restore the contents of my
|
||||
ipsets automatically under Shorewall-perl/Shorewall-lite (my
|
||||
routestopped file does not use ipsets).
|
||||
|
||||
2) A HELPER column is included in the tcrules file. The value in this
|
||||
column names one of the Netfilter protocol 'helper' module sets
|
||||
(ftp, sip, amanda, etc).
|

||||
