pfSense

Hi,
Have been seeing this since at least 2.4, and persists in 2.4.4-p2

WAN: vdsl, via modem on em1
ipv4 config: pppoe
ipv6 config: SLAAC

ISP provides link local only on wan, with an fe80::x gateway address.
When this interface comes up, pfsense sets the default route to the pppoe interfaces parent nic, rather than the pppoe1 interface.

This is easy to fix from console for a single ipv6 wan, simply change the default route and specify %pppoe1 rather than %em1
However I now have 2 ISPs who both support ipv6 - I am unable to get the second ISP working at all.

After a clean boot, this is what is required to get ipv6 traffic flowing:
