Package: shorewall6
Version: 5.2.3.2-1

Upon boot up shorewall6 fails to initialise IPv6 netfilter rules. Upon running 'ip6tables -L -v' the netfilter table is empty.

The problem is with the '/etc/init.d/shorewall6' script. At the beginning of this script a variable is set to the following, 'SRWL=/sbin/shorewall -6'. If this is changed to the following, 'SRWL=/sbin/shorewall6', the problem is resolved.

I am using Devuan Beowulf, with the stock kernel.
