cluster". Since the order in which I copy rule sets is
undefined and because they may have references to each other via
branching rules, I need to fix references after I create all
of them.
create redirect rule in cluster firewall object". Iptables nat
rule with target REDIRECT could not be built in a cluster
configuration. It should be possible to do this by putting cluster
object in Translated Destination.
addresses of vlan interfaces". This function used to take into
account only interfaces that were direct children objects of the
firewall. Since vlan interfaces are children of the corresponding
physical interface, they were not included.
"generated script gets .fw suffix even when user set output file
name". Suffix .fw should not be appended to the name entered by
the user in the "output file name" input field in the firewall
settings dialog.
"installer hangs and fails after activation of ipfw policy". As
soon as .fw script swapped ipfw sets usig command "ipfw sawp" and
deleted temporary set 1, ssh session would hang and eventually
break. We optionally add ipfw rules to permit ssh session used to
manage the firewall, as well as a rule to permit reply packets but
the latter rule was not built correctly. It should match source
and destination reversed, as well as match keyword "established"
and recreate state with "keep-state". This rule automatically
recreates state for the established ssh session over which
firewall policy is being managed. Also added a comment to the
firewall settings dialog for ipfw to remind the user that address
or subnet they use with this automatic rule should be as narrow as
possible.
wants to use putty session, show session name instead of the ip
address in the "Address that will be used to communicate with the
firewall" input field in the installer options dialog.
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.
problem" (type 4, any code) per SF feature request 3094743. Also
added service group object "ipv6 unreachable messages" that
includes ICMPv6 messages "destination unreachable", "packet too
big", "parameter problem" and "time exceeded" per SF feature
request 3094758
request 3094738 "Set the HL to 255 for IPv6 Neighbor
Discovery". Neighbor discovery packets must have hop limit of 255
per RFC 2461. Automatically generated rules that match neighbor
discovery packets will math hooplimit 255.
"Routing configuration failed". Iptables script generated by
fwbuilder did not configure broadcast when it added ip addresses
to interfaces. Using "ip addr add ADDR/NM boradcast + dev INTF"
syntax to do this.
of address assignment in the generated OpenBSD/PF/CARP cluster
configuration". Need to assign ip addresses to regular interfaces
before trying to assign them to carp interfaces.
"nf_conntrack_ipv6" if generated script has no ipv6 rules"
Shell function load_modules should not try to load module
nf_conntrack_ipv6 if generated script does not load any ipv6
rules. Loading this module fails if ipv6 has been disabled in
the kernel.
