Shorewall 2.2.2
|
||||
Shorewall 2.2.3
|
||||
|
||||
-----------------------------------------------------------------------
|
||||
Problems corrected in version 2.2.3
|
||||
|
||||
1) If a zone is defined in /etc/shorewall/hosts using
|
||||
<interface>:!<network> in the HOSTS column then startup errors occur
|
||||
on "shorewall [re]start".
|
||||
|
||||
2) Previously, if "shorewall status" was run on a system whose kernel
|
||||
lacked advanced routing support (CONFIG_IP_ADVANCED_ROUTER), then
|
||||
no routing information was displayed.
|
||||
|
||||
-----------------------------------------------------------------------
|
||||
New Features in version 2.2.3
|
||||
|
||||
1) A new extension script "continue" has been added. This script is
|
||||
invoked after Shorewall has set the built-in filter chains'
|
||||
policy to DROP, deleted any existing Netfilter rules and user
|
||||
chains and has enabled existing connections.
|
||||
|
||||
It is useful for enabling certain communication while Shorewall is
|
||||
being [re]started. Be sure to delete any rules that you add here in
|
||||
your /etc/shorewall/start file.
|
||||
|
||||
2) There has been ongoing confusion about how the
|
||||
/etc/shorewall/routestopped file works. People understand how it
|
||||
works with the 'shorewall stop' command but when they read that
|
||||
'shorewall restart' is logically equivalent to 'shorewall stop'
|
||||
followed by 'shorewall start' then they erroneously conclude that
|
||||
/etc/shorewall/routestopped can be used to enable new connections
|
||||
during 'shorewall restart'. Up to now, it cannot -- that file is not
|
||||
processed during either 'shorewall start' or 'shorewall restart'.
|
||||
|
||||
Beginning with Shorewall version 2.2.3, /etc/shorewall/routestopped
|
||||
will be processed TWICE during 'shorewall start' and during
|
||||
'shorewall restart'. It will be processed early in the command
|
||||
execution to add rules allowing new connections while the command
|
||||
is running and it will be processed again when the
|
||||
command is complete to remove the rules added earlier.
|
||||
|
||||
The result of this change will be that during most of [re]start, new
|
||||
connections will be allowed in accordance with the contents of
|
||||
/etc/shorewall/routestopped.
|
||||
|
||||
3) The performance of configurations with a large numbers of entries in
|
||||
/etc/shorewall/maclist can be improved by setting the new
|
||||
MACLIST_TTL variable in /etc/shorewall/shorewall.conf.
|
||||
|
||||
If your iptables and kernel support the "Recent Match" (see the
|
||||
output of "shorewall check" near the top), you can cache the results
|
||||
of a 'maclist' file lookup and thus reduce the overhead associated
|
||||
with MAC Verification.
|
||||
|
||||
When a new connection arrives from a 'maclist' interface, the packet
|
||||
passes through then list of entries for that interface in
|
||||
/etc/shorewall/maclist. If there is a match then the source IP
|
||||
address is added to the 'Recent' set for that interface. Subsequent
|
||||
connection attempts from that IP address occuring within
|
||||
$MACLIST_TTL seconds will be accepted without having to scan all
|
||||
of the entries. After $MACLIST_TTL from the first accepted
|
||||
connection request from an IP address, the next connection request
|
||||
from that IP address will be checked against the entire list.
|
||||
|
||||
If MACLIST_TTL is not specified or is specified as empty (e.g,
|
||||
MACLIST_TTL="" or is specified as zero then 'maclist' lookups
|
||||
will not be cached.
|
||||
|
||||
4) You can now specify QUEUE as a policy and you can designate a
|
||||
common action for QUEUE policies in /etc/shorewall/actions. This is
|
||||
useful for sending packets to something like Snort Inline.
