Bug#701200: default rules should be applied to both IPv4 and IPv6

[Philipp Kern <pkern@debian.org>]

Package: ferm
Version: 2.1-5
Severity: normal
Tags: ipv6

The ferm default ruleset only applies to IPv4. It does not touch IPv6 at all. I
think it should instead apply the same ruleset using domain (ip ip6) to both
address families. Sadly the IPsec rules do not work as-is with IPv6,
instead of ESP and AH "mod ipv6header header (esp ah) ACCEPT" needs to be used.
