Subject: No longer consider IN_EXPERIMENTAL aka 240/4 as not forwardable.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a96e5a4e7eee0bf74bc3996f6f2e9a55de158edf;p=openbsd

No longer consider IN_EXPERIMENTAL aka 240/4 as not forwardable.
We already allow 240/4 in and out so lets allow it through as well.
One of many steps to make 240/4 useable.
