Remove restrictions on source and destination addresses, which aren't specified on RFC8415, and for some reason in openwrt are configured to allow both link-local and ULA addresses. As cleared out in issue #5066 there are some ISPs that use Gloabal Unicast addresses, so fix this rule to allow them. Fixes: #5066 Signed-off-by: Tiago Gaspar <tiagogaspar8@gmail.com> [rebase onto firewall3, clarify subject, bump PKG_RELEASE] Signed-off-by: Jo-Philipp Wich <jo@mein.io>
