If you include the keyword trace as the first argument to any
of these commands:
start|stop|restart|reset|clear|refresh|check|add|delete

shorewall trace start 2> /tmp/trace
The above command would trace the 'start' command and
place the trace information in the file /tmp/trace.

Shorewall 1.4.11
Shorewall 2.0.16
Problems Corrected since version 1.4.10g
----------------------------------------------------------------------
Problems Corrected in version 2.0.4
1) The shorewall.conf and zones file are no longer given execute
permission by the installer.
1) A DNAT rule with 'fw' as the source that specified logging caused
"shorewall start" to fail.
----------------------------------------------------------------------
Problems Corrected in version 2.0.5
1) Eliminated "$RESTOREBASE: ambiguous redirect" messages during
"shorewll stop" in the case where DISABLE_IPV6=Yes in
shorewall.conf.
2) An anachronistic reference to the mangle option was removed from
shorewall.conf.
----------------------------------------------------------------------
Problems Corrected in version 2.0.6
1) Some users have reported the pkttype match option in iptables/
Netfilter failing to match certain broadcast packets. The result
is that the firewall log shows a lot of broadcast packets.
Other users have complained of the following message when
starting Shorewall:
modprobe: cant locate module ipt_pkttype
Users experiencing either of these problems can use PKTTYPE=No in
shorewall.conf to cause Shorewall to use IP address filtering of
broadcasts rather than packet type.
2) The shorewall.conf and zones file are no longer given execute
permission by the installer script.
3) ICMP packets that are in the INVALID state are now dropped by the
Reject and Drop default actions. They do so using the new
'dropInvalid' builtin action.
-----------------------------------------------------------------------
Problems Corrected in version 2.0.7
1) The PKTTYPE option introduced in version 2.0.6 is now used when
generating rules to REJECT packets. Broadcast packets are silently
dropped rather than being rejected with an ICMP (which is a protocol
violation) and users whose kernels have broken packet type match
support are likely to see messages reporting this violation.
Setting PKTTYPE=No should cause these messages to cease.
2) Multiple interfaces with the 'blacklist' option no longer result in
an error message at startup.
3) The following has been added to /etc/shorewall/bogons:
0.0.0.0 RETURN
This prevents the 'nobogons' option from logging DHCP 'DISCOVER'
broadcasts.
-----------------------------------------------------------------------
New Features in version 2.0.7
1) To improve supportability, the "shorewall status" command now
includes IP and Route configuration information.
Example:
IP Configuration

Problems Corrected in version 2.0.8
1) User/group restricted rules now work in actions.
-----------------------------------------------------------------------
Problems Corrected in version 2.0.9
1) Previously, an empty PROTO column or a value of "all" in that column
would cause errors when processing the /etc/shorewall/tcrules file.
New Fewatures in version 2.0.9
1) The "shorewall status" command now includes the output of "brctl
show" if the bridge tools are installed.
-----------------------------------------------------------------------
Problems corrected in version 2.0.10
1) The GATEWAY column was previously ignored in 'pptpserver' entries in
/etc/shorewall/tunnels.
2) When log rule numbers are included in the LOGFORMAT, duplicate
rule numbers could previously be generated.
3) The /etc/shorewall/tcrules file now includes a note to the effect
that rule evaluation continues after a match.
4) The error message produced if Shorewall couldn't obtain the routes
through an interface named in the SUBNET column of
/etc/shorewall/masq was less than helpful since it didn't include
the interface name.
-----------------------------------------------------------------------
New Features in 2.0.10
The "shorewall status" command has been enhanced to include the values
of key /proc settings:
Example from a two-interface firewall:
/proc
/proc/sys/net/ipv4/ip_forward = 1
/proc/sys/net/ipv4/conf/all/proxy_arp = 0

-----------------------------------------------------------------------
Problems corrected in 2.0.11
1) The INSTALL file now include special instructions for Slackware
users.
2) The bogons file has been updated.
3) Service names are replaced by port numbers in /etc/shorewall/tos.
4) A typo in the install.sh file that caused an error during a new
install has been corrected.
-----------------------------------------------------------------------
New Features in 2.0.11
1) The AllowNNTP action now allows NNTP over SSL/TLS (NTTPS).
-----------------------------------------------------------------------
Problems corrected in 2.0.12
1) A typo in shorewall.conf (NETNOTSYN) has been corrected.
2) The "shorewall add" and "shorewall delete" commands now work in a
bridged environment. The syntax is:
shorewall add <interface>[:<port>]:<address> <zone>
shorewall delete <interface>[:<port>]:<address> <zone>
Examples:
shorewall add br0:eth2:192.168.1.3 OK
shorewall delete br0:eth2:192.168.1.3 OK
3) Previously, "shorewall save" created an out-of-sequence restore
script. The commands saved in the user's /etc/shorewall/start script
were executed prior to the Netfilter configuration being
restored. This has been corrected so that "shorewall save" now
places those commands at the end of the script.
To accomplish this change, the "restore base" file
(/var/lib/shorewall/restore-base) has been split into two files:
/var/lib/shorewall/restore-base -- commands to be executed before
Netfilter the configuration is restored.
/var/lib/shorewall/restore-tail -- commands to be executed after the
Netfilter configuration is restored.
4) Previously, traffic from the firewall to a dynamic zone member host
did not need to match the interface specified when the host was
added to the zone. For example, if eth0:1.2.3.4 is added to dynamic
zone Z then traffic out of any firewall interface to 1.2.3.4 will
obey the fw->Z policies and rules. This has been corrected.
-----------------------------------------------------------------------
New Features in 2.0.12
1) Variable expansion may now be used with the INCLUDE directive.
Example:
/etc/shorewall/params
FILE=/etc/foo/bar
Any other config file:
INCLUDE $FILE
-----------------------------------------------------------------------
Problems corrected in 2.0.13
1) A typo in /usr/share/shorewall/firewall caused the following:
/usr/share/shorewall/firewall: line 1: match_destination_hosts: command
not found
-----------------------------------------------------------------------
New Features in 2.0.14
1) Previously, when rate-limiting was specified in
/etc/shorewall/policy (LIMIT:BURST column), any traffic which
exceeded the specified rate was silently dropped. Now, if a log
level is given in the entry (LEVEL column) then drops are logged at
that level at a rate of 5/min with a burst of 5.
-----------------------------------------------------------------------
Problems corrected in 2.0.14
1) A typo in the /etc/shorewall/interfaces file has been fixed.
2) "bad variable" error messages occurring during "shorewall stop" and
"shorewall clear" have been eliminated.
3) A misleading typo in /etc/shorewall/tunnels has been corrected.
-----------------------------------------------------------------------
Problems corrected in 2.0.15
1) The range of ports opened by the AllowTrcrt action has been
expanded to 33434:33524.
2) Code mis-ported from 2.2.0 caused the following error during
"shorewall start" where SYN rate-limiting is present in
/etc/shorewall/policy:
Bad argument `DROP'
Try `iptables -h' or 'iptables --help' for more information.
-----------------------------------------------------------------------
New Features in 2.0.16
1) Recent 2.6 kernels include code that evaluates TCP packets based on
TCP Window analysis. This can cause packets that were previously
classified as NEW or ESTABLISHED to be classified as INVALID.
The new kernel code can be disabled by including this command in
your /etc/shorewall/init file:
echo 1 > /proc/sys/net/ipv4/netfilter/ip_conntrack_tcp_be_liberal
Additional kernel logging about INVALID TCP packets may be
obtained by adding this command to /etc/shorewall/init:
echo 1 > /proc/sys/net/ipv4/netfilter/ip_conntrack_log_invalid
Traditionally, Shorewall has dropped INVALID TCP packets early. The
new DROPINVALID option allows INVALID packets to be passed through
the normal rules chains by setting DROPINVALID=No.
If not specified or if specified as empty (e.g., DROPINVALID="")
then DROPINVALID=Yes is assumed.
