single object negation in "Inbound Interface" and "Outbound
Interface" columns in compiler for iptables.
* NATCompiler_pf.cpp (compile): see #2456 Added support for single
object negation in "Interface" rule element of PF NAT rules. Now
compiler can produce PF commands such as "nat on ! em0 ... " (for
PF <4.7) or "match on ! em0 ..." (for PF >= 4.7)
* Compiler.cpp (singleObjectNegation::processNext): moved rule
processor that processes single object negation in any rule
element to the base class Compiler.
should be done in PREROUTING so it can be acted on later". If a
rule has both tagging and classification options, the rule should
be split so that iptables command doing tagging goes in PREROUTING
and rule doing classification goes into POSTROUTING chain.

compiling single rule with IPv6 destination and IPv4 gateway or
interface". Routing compiler for iptables does not support ipv6 at
this time and will issue a warning when user tries to place ipv6
address or network in a routing rule. The warning does not appear
when ipv6 address is a member of a group used in the rule. Also
see #1575.
3178186 "Add ND/NS allow rules for the FORWARD chain". Rules that are
added automatically to ipv6 Linux firewall to permit neighbor discovery
packets should be also added to the FORWARD chain if the firewall is
a bridge.

name "ppp-dsl" for PPPoE interfaces. In addition to that, Linux
bridge interfaces may have names with a "-" such as
"br-lan". We will now permit a "-" in Linux interface names.
fixed SF bug 3094273 "no state needed for ipv6-icmp in
ip6tables". Rules that match ICMPv6 objects should be
stateless. Compiler will check for this and reset "stateful" flag
of a rule and issue warning if the rule was built stateful in the
GUI.
"iptables redirecting NAT rules in the OUTPUT chain". NAT rules
should be allowed to translate from CustomService to TCP or UDP
service, provided CustomService object is configured with matching
protocol. See also change in libfwbuilder NATCompiler::classifyNATRule::processNext.
"iptables redirecting NAT rules in the OUTPUT chain". This fix
makes it possible to create iptables NAT rule with target REDIRECT
in the OUTPUT chain. The rule should have firewall object in OSrc
and TDst rule elements.
only firewall resets ipv4 stack" only reset ipv4 iptables when there are some ip4 rules; also added action block to usage string of the generated iptables script
"set" used to generate iptables command for rules with run-time
AddressTable objects. This module is only available in iptables
1.4.1.1 and later, however some embedded platforms do not have it
even though they ship later versions ofiptables (e.g. OpenWRT).
Use of this module is controlled by a checkbox in the iptables
"advanced" settings dialog which is off by default. This checkbox
becomes disabled when iptables version is set to < 1.4.1.1.
fixed#1523 "outbound ipv6 rule matching multicast ipv6 destination
is not generated". The rule with network object fe80::/10 in source
and ipv6 muticast ff00::/8 in destination did not produce correspondign
ip6tables command. The change affects other cases with rules using
broadcast or multicast objects that should be considered matching
the firewall object.
support some popular iptables modules". Added support for module
"recent" and rules that match standard ip/icmp/udp/tcp protocols
and at the same time module "mark", "length", "limit" or "recent".
Rules like these are translated into a combination of a branching
rule and additional rule in a branch rule set that implements
module match.
QProcess::waitForFinished() instead of just sleep() after we send
TERM signal to the background process. Also let Qt process events
to update the GUI while waiting.
* instDialog_installer.cpp (instDialog::stopInstall): fixed#1428
button "Stop" in the installer dialog does not stop installer
process
fixes#1417 rule shadowing detection should recognize different rule options.
Policy compiler for iptables takes into account rule options for modules
limit, connlimit and hashlimit when it considers rules for rule shadowing.
