- Perl 5.10 if you wish to use DNS names in your IPv6 config files.
|
||||
In that case you will also have to install Perl Socket6 support.

Problems Corrected in 4.3.2

Problems Corrected in 4.3.3
|
||||
|
||||
1) Typos in the macro.AllowICMPs file have been corrected.
|
||||
None.
|
||||
|
||||
2) IP_FORWARDING is now correctly recognized by Shorewall-perl.
|
||||
Other changes in 4.3.3
|
||||
|
||||
3) A bug in processing of the routestopped file has been fixed. This
|
||||
bug also affected IPv4 configurations.
|
||||
1) In as much as ip6tables doesn't support the ECN target, the 'ecn'
|
||||
file has been removed and its processing disabled.
|
||||
|
||||
Other changes in 4.3.2
|
||||
2) The 'maclist' option is now supported in /etc/shorewall6/interfaces
|
||||
and in /etc/shorewall6/hosts.
|
||||
|
||||
1) The 'dhcp' option has been added to accomodate IPv6 DHCP (UDP ports
|
||||
546 and 547).
|
||||
MAC verification is not performed on the following IPv6 traffic:
|
||||
|
||||
2) The 'allowBcast' and 'dropBcast' builtin actions have been added to
|
||||
Shorewall6. Respectively, they accept or silently drop packets with
|
||||
an anycast or multicast destination address.
|
||||
|
||||
3) The nosmurfs option has been added to
|
||||
/etc/shorewall8/interfaces. The option drops incoming packets with
|
||||
a source address that is an anycast or multicast addreess.
|
||||
|
||||
4) Multi-ISP is now enabled in Shorewall6.
|
||||
|
||||
5) When running the 'ip' utility, Shorewall now unconditionally
|
||||
specifies the address family (-4 or -6).
|
||||
a) Multicast.
|
||||
b) Source or destination is a link-level address (ff80::/10).
|
||||
|
||||
Migration Issues.
