Thank you. Your assumptions are right. I filter on application on the
workstation, and on port/destination on the router.

Iptables lost --cmd-owner, so new kernels were pretty useless to me,
but they seem to be reintroduced for ip6tables. Is there a "howto" to
rewrite a iptables firewall-ruleset to ip6tables (or a good
introduction for ip6tables)?
