1)  In all versions of Shorewall6 lite, the 'shorecap' program is
    using the 'iptables' program rather than the 'ip6tables' program.
    This causes many capabilities that are not available in IPv6 to
    be incorrectly reported as available.

    This results in errors such as:

    	 ip6tables-restore v1.4.2: Couldn't load match `addrtype':
	   /lib/xtables/libip6t_addrtype.so: cannot open shared
	   object file: No such file or directory

    To work around this problem, on the administrative system:

    a)  Remove the incorrect capabilties file.
    b)  In shorewall6.conf, set the IP6TABLES option to the
        path name of ip6tables on the firewall (example:
	IP6TABLES=/sbin/ip6tables).
    c)  'shorewall6 load <firewall>'.

2)  In a number of cases, Shorewall6 generates incorrect rules
    involving the IPv6 multicast network. The rules specify
    ff00::/10 where they should specify ff00::/8.  Also, rules
    instantiated when the IPv6 firewall is stopped use ff80::/10 rather
    than fe80::/10 (IPv6 link local network).

3)  Using a destination port-range with :random produces a fatal
    compilation error in REDIRECT rules.

4)  Shorewall-init is not reliable in bringing up interfaces during
    boot on Ubuntu systems that use upstart.

    Suggested workaround is to set startup=1 in your
    /etc/default/shorewall* files.
