Problems Corrected in 4.3.2
|

|

1) Shorewall6 parsing of the hosts file HOSTS column has been
|

corrected.

None.

Other changes in 4.3.2
|
||||
|
||||
1) It is now permitted to enclose addresses in [] even when an
|
||||
interface name is not specified.
|
||||
|
||||
Example:
|
||||
|
||||
ACCEPT net:[2001:1::1] $FW
|
||||
|
||||
2) The Socket6 perl module is only required now if DNS names appear in
|
||||
your Shorewall6 configuration files.
|
||||
|
||||
3) Shorewall6 now recognizes IPv4 addresses embedded in the IPv6
|
||||
address space (e.g., ::ffff:192.168.1.3).
|
||||
|
||||
4) IP_FORWARDING has been added back into shorewall6.conf and works
|
||||
like the corresponding option in Shorewall.
|
||||
1) The 'dhcp' option has been added to accomodate IPv6 DHCP (UDP ports
|
||||
546 and 547).

The HOSTS column in /etc/shorewall6/hosts also uses this
|
||||
convention:

|

#ZONE HOSTS OPTIONS

chat6 eth0:[2001:19f0:feee::dead:beef:cafe]

Even when an interface is not specified, it is permitted to
|
||||
enclose addresses in [] to improve readability. Example:
|
||||
|
||||
#ACTION SOURCE DEST
|
||||
ACCEPT net:[2001:1::1] $FW
|
||||
|
||||
g) There are currently no Shorewall6 or Shorewall6-lite manpages.
