fixes#1084 "if all user turns off all interface management and
configuration checkboxes, the check_tools shell function is not
added to the script but still called". Shell function
"check_tools" verifies that system tools iptables script needs to
operate properly are installed on the firewall. These are: ip,
modprobe and optionally vconfig, brctl, ifenslave. The bug made
compiler for iptables to add the call to the function but function
definition was missing if user unchecked all "configure
interfaces" checkboxes in the Script tab of firewall object
settings dialog.
* CompilerDriver_ipt_run.cpp (CompilerDriver_ipt::run): Refs #869
making sure non-english comments appear correctly in the single
rule compile output and generated configuration files and scripts.
really fixed#869 "compile rule" should also print the comment.
Printing rule comment in the compiler output in the single rule
compile mode when firewall object is configured to use
iptables-restore. Code that prints rule label and comment has been
unified for compilers for all firewall platforms.
#1064: "Dedicated IPv6 interfaces show up in IPv4-NAT rules". Use
interface only if it has addresses that match address family we
compile for.
fixes#1064
compiler for IOS ACL added only inbound automatic rule to permit
ssh access from the management workstation but did not add a rule
to permit reply packets. This fixes#993
* src/res/configlets/linux24/automatic_rules: Generation of the
automatic rules (matching ESTABLISHED and INVALID states,
backup ssh access and others) now uses configlet. Fixes#883
* src/res/configlets/linux24/automatic_rules: generated script can
now include automatic rules to match IPv6 neighbor discovery ICMP6
packets. This is controlled by a checkbox in the iptables
"advanced" settings dialog and is off by default. Fixes#878
* CompilerDriver_pix_run.cpp (CompilerDriver_pix::run): Added
support for failover configurations for PIX.
- Interfaces of member firewalls used for failover configuration
should be marked as "Dedicated failover" interfaces. They should
have normal IP addresses. These interfaces will be used to
generate "failover" commands in the PIX configuration.
- Cluster should have interface with the same name as failover
interfaces of the members, with protocol set to "PIX failover" and
members configured as usual. This interface has no ip address.
- Other interfaces of the cluster have the same name as
corresponding interfaces of the member firewalls, protocol "None"
and failover groups that define members as usual. These cluster
interfaces also have no ip address.
- Cluster state synchronization group uses protocol "PIX state
synchrnization" and its members should be configured as usual.
Use failover interfaces of the members as members of the state
sync group.
* Interface.cpp: Added attribute "dedicated_failover" to the
Interface object. Interfaces with this attribute are treated like
other "unprotected" interfaces, that is they are not used to
attach ACLs to and not used in rules. Dedicated failover
interfaces have special meaning in PIX configurations and are used
to describe interfaces used for LAN failover.
Implemented TCP flag matching per #2865044: "Add TCP options
support for IOS ACL". Uses extended ACL option "match-all" that
supports list of TCP flags that should be set and cleared. This
requires IOS v12.4 or later even though Cisco documentation seems
to indicate this option was introduced in 12.3(4)T. Fixes#455
does not support IP options matching, compiler issues warning.
Fixes#567
* res/platform/iosacl.xml: Recognized IOS versions: 12.1, 12.2,
12.3
* PolicyCompiler_iosacl_writers.cpp (PrintRule::_printIPServiceOptions):
Added support for IP options matching, requires IOS v12.3 or
later. Fixes#566, #568
* NATCompiler_ipt.cpp (dynamicInterfaceInTSrc::processNext):
Implemented feature request #2829661: "SNAT instead of MASQUERADE
on dynamic interfaces". NAT rule options dialog now has a checkbox
that makes compiler use SNAT target instead of MASQUERADING when
checked when TSrc has dynamic interface. Apparently MASQ target
has problems when iptables NAT is used in combination with policy
routing. Using SNAT with a variable that gets interface address
solves the problem. By default this option is off, that is
compiler uses MASQUERADE target when TSrc has dynamic interface.
Fixes#560
* CompilerDriver_pf.cpp (CompilerDriver_pf::printStaticOptions):
Added support for PF configuration parameter "set state-policy"
which can have values "if-bound" or "floating". The GUI input
element provides these options in addition to the default empty
option. If empty list item is selected, command "set state-policy"
is not added to the generated .conf file at all. Fixes#423
