Enable filtering on ipfw sysctl not dependent on ipfw module otherwise issue reported here http://forum.pfsense.org/index.php/topic,64412.0.html happens
For ppp interfaces the real interface is not present anymore in the xml config section of the interface. Due to this do some more work on extracting the real interface when ipv4 is pppoe/ppp/... and ipv6 configuration files will use the wrong interface to request information from provider.

Do not break ppp type interfaces on v6
Don't generate reflection rules if reflection is disabled for that rule.
