Shorewall 2.0.11

----------------------------------------------------------------------
Problems Corrected in version 2.0.4

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

      link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

-----------------------------------------------------------------------
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
   /proc/sys/net/ipv4/conf/all/arp_filter = 0
   /proc/sys/net/ipv4/conf/all/rp_filter = 0
   /proc/sys/net/ipv4/conf/default/proxy_arp = 0
   /proc/sys/net/ipv4/conf/default/arp_filter = 0
   /proc/sys/net/ipv4/conf/default/rp_filter = 0
   /proc/sys/net/ipv4/conf/eth0/proxy_arp = 0
   /proc/sys/net/ipv4/conf/eth0/arp_filter = 0
   /proc/sys/net/ipv4/conf/eth0/rp_filter = 0
   /proc/sys/net/ipv4/conf/eth1/proxy_arp = 0
   /proc/sys/net/ipv4/conf/eth1/arp_filter = 0
   /proc/sys/net/ipv4/conf/eth1/rp_filter = 0
   /proc/sys/net/ipv4/conf/lo/proxy_arp = 0
   /proc/sys/net/ipv4/conf/lo/arp_filter = 0
   /proc/sys/net/ipv4/conf/lo/rp_filter = 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).
