pfSense

I started with a forum post here [[http://forum.pfsense.org/index.php/topic,68364.0.html]] with details as well.

There appears to be a change between June 24th RC0 and Release 2.1 that has caused this issue.

I use PPPoE with IPv6. The provider only supports SLAAC for address assignment. Under 2.1 release the default gateway for IPv6 traffic is wrongly assigned to LINK_LOCAL_ADDR%vr1 (my wan interface port). Under RC0 this was assigned as LINK_LOCAL_ADDR%pppoe0.

I have confirmed that manually changing the default route resolves the issues. I'm not able to verify 100% where this is going wrong but cmb said to file a bug report with the data I have. He also noted that this isn't a wide spread use case. I will gladly test or get additional information if needed.

I've collected an ifconfig and netstat -rn listing from both RC0 and 2.1 release that I've noticed issues with.
